Medpedia, the Medical Wikipedia, is Dead. And we Missed its Funeral…

12 07 2013

In a post about Wikipedia in 2009 I suggested that initiatives like Ganfyd or Medpedia, might be a solution to Wikipedia’s accuracy and credibility problems, because only health experts are allowed to edit or contribute to the content of these knowledge bases.

MedPedia is a more sophisticated platform than Ganfyd, which looks more like a simple medical encyclopedia. A similar online encyclopedia project with many medical topics, Google Knol, was discontinued by Google as of May 1, 2012.

But now it appears Medpedia may have followed Google KNOL into the same blind alley.

Medpedia was founded in 2007 [2a] by James Currier, an entrepreneur and investor [2b], and an early proponent of social media. He founded the successful Tickle in 1999, when the term Web 2.0 was coined, but not yet mainstream. And his list of  investments is impressive: Flickr, Branchout and Goodreads for instance.

On its homepage Medpedia was described as a “long term, worldwide project to evolve a new model for sharing and advancing knowledge about health, medicine and the body.”
It was developed in association with top medical schools and organizations such as Harvard, Stanford, American College of Physicians, and the NHS. Medpedia was running on the same software and under the same license as Wikipedia and aimed both at the public and  the experts. Contrary to Wikipedia only experts were qualified to contribute to the main content (although others could suggest changes and new topics). [3, 4 , 5, 6] In contrast to many other medical wikis, Medpedia featured a directory of medical editor profiles with general and Medpedia-specific information. This is far more transparent than wikis without individual author recognition [5].

Although promising, Medpedia never became a real success. Von Muhlen wrote in 1999 [4] that there were no articles reporting success metrics for Medpedia or similar projects. In contrast, Wikipedia remains immensely popular among patients and doctors.

Health 2.0 pioneers like E-Patient Dave (@ePatientDave) and Bertalan Meskó (@berci) saw Medpedia’s Achilles heel right from the start:

Bertalan Meskó at his blog Science Roll [7]:

We need Medpedia to provide reliable medical content? That’s what we are working on in Wikipedia.

I believe elitism kills content. Only the power of masses controlled by well-designed editing guidelines can lead to a comprehensive encyclopaedia.

E-patient Dave (who is a fierce proponent of participatory medicine where everyone, medical expert or not, works in partnership to produce accurate information), addresses his concern in his post

“Medpedia: Who gets to say what info is reliable?” [8]

The title says it all. In Dave’s opinion it is “an error to presume that doctors inherently have the best answer” or as Dave summarizes his concern: “who will vet the vetters?”

In addition, Clay Shirky noted that some Wikipedia entries like the biopsy-entry were far more robust than the Medpedia entries [9,10 ].

Ben Toth on the other hand found the Atrial Fibrillation-Medpedia item better than the corresponding Wikipedia page in some respects, but less up-to-date [11].

In her Medpedia review in the JMLA medical librarian Melissa Rethlefsen [5] concludes that “the content of Medpedia is varied and not clearly developed, lacks topical breadth and depth and that it is more a set of ideals than a workable reference source. Another issue is that Medpedia pages never ranked high, which means its content was hardly findable in today’s Google-centric world.

She concludes that for now (2009) “it means that Wikipedia will continue to be the medical wiki of choice”.

I fear that this will be forever, for Medpedia ceased to exist.

I noticed it yesterday totally by coincidence: both my Medpedia blog badge  and Mesko’s Webicina-“Medical Librarianship in Social Medicine”-wiki page were redirected to a faulty page.

I checked the Internet, but all I could find was a message at Wikipedia:

‘It appears that Medpedia is now closed but there is no information about it closing. Their Facebook and Twitter feeds are still open but they have not been updated in a few years. Their webpage now goes to a spam site.

I checked the Waybackmachine and found the “last sparks of life” at January 2013:

11-7-2013 23-57-49 waybackmachine medpedia

This morning I contacted Medpedia’s founder James Currier, who kindly and almost instantly replied to all my questions.

These are shown (with permission) in entirety below.


[me: ] I hope that you don’t mind that I use LinkedIn to ask you some questions about Medpedia.

{James:] I don’t mind at all!

Is Medpedia dead? And if so, why was it discontinued?

For now it is. We worked on it for 6 years, had a fantastic team of developers, had fantastic partners who supported us, had a fantastic core group of contributors like yourself, and I personally spent millions of dollars on it. In other words, we gave it a really good effort. But it never got the sort of scale it needed to become something important. So for the last two years, we kept looking for a new vision of what it could become, a new mission. We never found one, and it was expensive to keep running.
In the meantime, we had found a new mission that Medpedia could not be converted into, so we started a new company, Jiff, to pursue it. “Health Care in a Jiff” is the motto. Jiff continues the idea of digitizing healthcare, and making it simple and transparent for the individual, but goes after it in a very different way. More info about Jiff here: and here has taken our time and attention, and hopefully will produce the kinds of benefits we were hoping to see from Medpedia.

Why weren’t people informed and  was Medpedia quietly shut down?

We definitely could have done a better job with that! I apologize. We were under a tight time frame due to several things, such as people leaving the effort, technical issues around where the site was being hosted, and corporate and tax issues after 6 years of operating. So it was rushed, and we should have figured out a way to do a better job of communicating.

Couldn’t the redirection to the spam-site be prevented? And can you do something about it?

I didn’t know about that! I’ll look into it and find out what’s going on.*

Your LinkedIn profile says you’re still working for MedPedia. Why is that? Are there plans to make a new start, perhaps? And how?

Yes, I haven’t updated my LinkedIn profile in a while. I just made that change. We have no current plans to restart Medpedia. But we’re always looking for a new mission that can be self sustaining! Let me know if you have one.

And/or do you have (plans for) other health 2.0 initiatives?

Jiff is our main effort now, and there’s a wonderful CEO, Derek Newell running it.

I know you are a busy man, but I think it is important to inform all people who thought that Medpedia was a good initiative.

Thank you for saying you thought it was a good initiative. I did too! I just wish it had gotten bigger. I really appreciate your questions, and your involvement. Not all projects flourish, but we’ll all keep trying new ideas, and hopefully one will break out and make the big difference we hope for.

*somewhat later James gave an update about the redirection:

By the way, I asked about the redirect, and found out that that that page is produced by our registrar that holds the URL

We wanted to put up the following message and I thought it was up:

“Medpedia was a great experiment begun in 2007.
Unfortunately, it never reached the size to be self sustaining, and it ceased operations in early 2013.
Thank you to all who contributed!”

I’m going to work again on getting that up!


I have one question left : what happened with all the materials the experts produced? Google Knol gave people time to export their contributions. Perhaps James Currier can answer that question too.

I also wonder why nobody noticed that Medpedia was shut down. Apparently it isn’t missed.

Finally I would like to thank all wo have contributed to this “experiment”. As a medical librarian, who is committed to providing reliable medical information, I still find it a shame that Medpedia didn’t work.

I wish James Currier all the best with his new initiatives.

#EAHIL2012 CEC 2: Visibility & Impact – Library’s New Role to Enhance Visibility of Researchers

4 07 2012

This week I’m blogging at (and mostly about) the 13th EAHIL conference in Brussels. EAHIL stands for European Association for Health Information and Libraries.

The second Continuing Education Course (CEC) I followed was given by Tiina Heino and Katri Larmo of the Terkko Meilahti Campus Library at the University of Helsinki in Finland.

The full title of the course was Visibility and impact – library’s new role: How the library can support the researcher to get visibility and generate impact to researcher’s work. You can read the abstract here.

The hands-on workshop mainly concentrated on the social bookmarking sites ConnoteaMendeley and Altmetric.

Furthermore we got information on CiteULike, ORCID,  Faculty of 1000 Posters and Pinterest. Also services developed in Terkko, such as ScholarChart and TopCited Articles, were shortly demonstrated.

What I especially liked in the hands on session is that the tutors had prepared a wikispace with all the information and links on the main page ( and a separate page for each participant to edit (here is my page). You could add links to your created accounts and embed widgets for Mendeley.

There was sufficient time to practice and try the tools. And despite the great number of participants there was ample room for questions (& even for making a blog draft ;)).

The main message of the tutors is that the process of publishing scientific research doesn’t end at publishing the article: it is equally important what happens after the research has been published. Visibility and impact in the scientific community and in the society are  crucial  for making the research go forward as well as for getting research funding and promoting the researcher’s career. The Fig below (taken from the presentation) visualizes this process.

The tutors discussed ORCID, Open Researcher and contributor ID, that will be introduced later this year. It is meant to solve the author name ambiguity problem in scholarly communication by central registry of unique identifiers for each author (because author names can’t be used to reliably identify all scholarly author). It will be possible for authors to create, manage and share their ORCID record without membership fee. For further information see several publications and presentations by Martin Fenner. I found this one during the course while browsing Mendeley.

Once published the author’s work can be promoted using bookmarking tools, like CiteULike, Connotea and Mendeley. You can easily registrate for Connotea and Mendeley using your Facebook account. These social bookmarking tools are also useful for networking, i.e. to discover individuals and groups with the same field of interest. It is easy to synchronize your Mendeley with your CiteULike account.

Mendeley is available in a desktop and a web version. The web version offers a public profile for researchers, a catalog of documents, and collaborative groups (the cloud of Mendeley). The desktop version of Mendeley is specially suited for reference management and organizing your PDF’s. That said Mendeley seems most suitable for serendipitous use (clicking and importing a reference you happen to see and like) and less useful for managing and deduplicating large numbers of records, i.e. for a systematic review.
Also (during the course) it was not possible to import several PubMed records at once in either CiteULike or Mendeley.

What stroke me when I tried Mendeley is that there were many small or dead groups. A search for “cochrane”  for instance yielded one large group Cochrane QES Register, owned by Andrew Booth, and 3 groups with one member (thus not really a group), with 0 (!) to 6 papers each! It looks like people are trying Mendeley and other tools just for a short while. Indeed, most papers I looked up in PubMed were not bookmarked at all. It makes you wonder how widespread the use of these bookmarking tools is. It probably doesn’t help that there are so many tools with different purposes and possibilities.

Another tool that we tried was Altmetric. This is a free bookmarklet on scholarly articles which allows you to track the conversations around scientific articles online. It shows the tweets, blogposts, Google+ and Facebook mentions, and the numbers of bookmarks on Mendeley, CiteULike and Connotea.

I tried the tool on a paper I blogged about , ie. Seventy-Five Trials and Eleven Systematic Reviews a Day: How Will We Ever Keep Up?

The bookmarklet showed the tweets and the blogposts mentioning the paper.

Indeed altmetrics did correctly refer to my blog (even to 2 posts).

I liked altmetrics*, but saying that it is suitable for scientific metrics is a step too far. For people interested in this topic I would like to refer -again- to a post of Martin Fenner on altmetrics (in general).  He stresses that “usage metrics”  has its limitations because of its proness  to “gaming” (cheating).

But the current workshop didn’t address the shortcomings of the tools, for it was meant as a first practical acquaintance with the web 2.0 tools.

For the other tools (Faculty of 1000 Posters, Pinterest) and the services developed in Terkko, such as ScholarChart and TopCited Articles,  see the wikipage and the presentation:

*Coincidentally I’m preparing a post on handy chrome extensions to look for tweets about a webpage. Altmetric is another tool which seems very suitable for this purpose

Medical Black Humor, that is Neither Funny nor Appropriate.

19 09 2011

Last week, I happened to see this Facebook post of the The Medical Registrar where she offends a GP, Anne Marie Cunningham*, who wrote a critical post about black medical humor at her blog “Wishful Thinking in Medical Education”. I couldn’t resist placing a likewise “funny” comment in this hostile environment where everyone seemed to agree (till then) and try to beat each other in levels of wittiness (“most naive child like GP ever” – “literally the most boring blog I have ever read”,  “someone hasn’t met many midwives in that ivory tower there.”, ~ insulting for a trout etc.):

“Makes no comment, other than anyone who uses terms like “humourless old trout” for a GP who raises a relevant point at her blog is an arrogant jerk and an unempathetic bastard, until proven otherwise…  No, seriously, from a patient’s viewpoint terms like “labia ward” are indeed derogatory and should be avoided on open social media platforms.”

I was angered, because it is so easy to attack someone personally instead of discussing the issues raised.

Perhaps you first want to read the post of Anne Marie yourself (and please pay attention to the comments too).

Social media, black humour and professionals…

Anne Marie mainly discusses her feelings after she came across a discussion between several male doctors on Twitter using slang like ‘labia ward’ and ‘birthing sheds’ for birth wards, “cabbage patch” to refer to the intensive care and madwives for midwives (midwitches is another one). She discussed it with the doctors in question, but only one of them admitted he had perhaps misjudged sending the tweet. After consulting other professionals privately, she writes a post on her blog without revealing the identity of the doctors involved. She also puts it in a wider context by referring to  the medical literature on professionalism and black humour quoting Berk (and others):

“Simply put, derogatory and cynical humour as displayed by medical personnel are forms of verbal abuse, disrespect and the dehumanisation of their patients and themselves. Those individuals who are the most vulnerable and powerless in the clinical environment – students, patients and patients’ families – have become the targets of the abuse. Such humour is indefensible, whether the target is within hearing range or not; it cannot be justified as a socially acceptable release valve or as a coping mechanism for stress and exhaustion.”

The doctors involved do not make any effort to explain what motivated them. But two female anesthetic registrars frankly comment to the post of Anne Marie (one of them having created the term “labia ward”, thereby disproving that this term is misogynic per se). Both explain that using such slang terms isn’t about insulting anyone and that they are still professionals caring for patients:

 It is about coping, and still caring, without either going insane or crying at work (try to avoid that – wait until I’m at home). Because we can’t fall apart. We have to be able to come out of resus, where we’ve just been unable to save a baby from cotdeath, and cope with being shouted and sworn at be someone cross at being kept waiting to be seen about a cut finger. To our patients we must be cool, calm professionals. But to our friends, and colleagues, we will joke about things that others would recoil from in horror. Because it beats rocking backwards and forwards in the country.

[Just a detail, but “Labia ward” is a simple play on words to portray that not all women in the “Labor Ward” are involved in labor. However, this too is misnomer.  Labia have little to do with severe pre-eclampsia, intra-uterine death or a late termination of pregnancy]

To a certain extent medical slang is understandable, but it should stay behind the doors of the ward or at least not be said in a context that could offend colleagues and patients or their carers. And that is the entire issue. The discussion here was on Twitter, which is an open platform. Tweets are not private and can be read by other doctors, midwives, the NHS and patients. Or as e-Patient Dave expresses so eloquently:

I say, one is responsible for one’s public statements. Cussing to one’s buddies on a tram is not the same as cussing in a corner booth at the pub. If you want to use venting vocabulary in a circle, use email with CC’s, or a Google+ Circle.
One may claim – ONCE – ignorance, as in, “Oh, others could see that??” It must, I say, then be accompanied by an earnest “Oh crap!!” Beyond that, it’s as rude as cussing in a streetcorner crowd.

Furthermore, it seemed the tweet served no other goal as to be satirical, sardonic, sarcastic and subversive (words in the bio of the anesthetist concerned). And sarcasm isn’t limited to this one or two tweets. Just the other day he was insulting to a medical student saying among other things:“I haven’t got anything against you. I don’t even know you. I can’t decide whether it’s paranoia, or narcissism, you have”. 

We are not talking about restriction of “free speech” here. Doctors just have to think twice before they say something, anything on Twitter and Facebook, especially when they are presenting themselves as MD.  Not only because it can be offensive to colleagues and patients, but also because they have a role model function for younger doctors and medical students.

Isolated tweets of one or two doctors using slang is not the biggest problem, in my opinion. What I found far more worrying, was the arrogant and insulting comment at Facebook and the massive support it got from other doctors and medical students. Apparently there are many “I-like-to-exhibit-my-dark-humor-skills-and-don’t-give-a-shit-what-you think-doctors” at Facebook (and Twitter) and they have a large like-minded medical audience: the “medical registrar page alone has 19,000 (!) “fans”.

Sadly there is a total lack of reflection and reason in many of the comments. What to think of:

“wow, really. The quasi-academic language and touchy-feely social social science bullshit aside, this woman makes very few points, valid or otherwise. Much like these pages, if you’re offended, fuck off and don’t follow them on Twitter, and cabbage patch to refer to ITU is probably one of the kinder phrases I’ve heard…”


“Oh my god. Didnt realise there were so many easily offended, left winging, fun sponging, life sucking, anti- fun, humourless people out there. Get a grip people. Are you telling me you never laughed at the revue’s at your medical schools?”


“It may be my view and my view alone but the people who complain about such exchanges, on the whole, tend to be the most insincere, narcissistic and odious little fuckers around with almost NO genuine empathy for the patient and the sole desire to make themselves look like the good guy rather than to serve anyone else.”

It seems these doctors and their fans don’t seem to possess the communicative and emphatic skills one would hope them to have.

One might object that it is *just* Facebook or that “#twitter is supposed to be fun, people!” (dr Fiona) 

I wouldn’t agree for 3 reasons:

  • Doctors are not teenagers anymore and need to act as grown-ups (or better: as professionals)
  • There is no reason to believe that people who make it their habit to offend others online behave very differently IRL
  • Seeing Twitter as “just for fun” is an underestimation of the real power of Twitter

Note: *It is purely coincidental that the previous post also involved Anne Marie.

Webicina Goes Mobile with a Free iPhone App.

15 03 2011

At this blog I have mentioned Bertalan (Berci) Mesko a couple of times. Berci, a MD who does a PhD in personalized genetics, is most famous for his award-winning blog Scienceroll, his health 2.0 presentations and  his creation of Webicina, a  free service that curates medical social media resources for medical professionals and e-patients.

Webicina has greatly evolved, since I’ve reviewed it 2 years ago in “PeRSSonalized Medicine – and its alternatives: it covers 80 topics, 3000 resources and 17 languages. Most importantly patients and doctors find it extremely useful to keep up-to-date via this customizable aggregator of quality medical resources in social media (Medical Journals, Blogs, News and Web 2.0 tools). I often see it mentioned on Twitter.

I’m glad to announce that Webicina is now available as a free mobile app. This application makes it easier to access the information on Webicina. It also includes a Health 2.0 Quiz which was designed to help empowered patients and medical professionals know more about the world of medicine and social media. You can download the Webicina app for free in the iTunes store. It is also compatible with iPod touch, and the  iPad.

Unfortunately I couldn’t test the app for you, because I have no I-phone. But I understood I don’t have to wait for long before the Android version comes out.

Meanwhile Ivor Kovic did test the Webicina app. This is his opinion:

The app is very nicely designed, and the cool thing is that you can browse through all the listed resources inside the app, without the need to go back and forward between your web browser. In just a few minutes of playing around with it, I found some great new resources and reminded myself of all the great content inside the Emergency Medicine category in which this blog is also featured. I can already see that I will be spending many hours exploring valuable new content on my phone using Webicina app, and if you want to stay on top of your game in your field, I strongly suggest you do the same.

Practicing Medicine in the Web 2.0 Era

29 01 2010

Many people don’t get Web 2.0 – and certainly not Medicine 2.0.

Just the other day a journalist asked me if the redesigned PubMed could be called PubMed 2.0.
I said: “well no….no… not at all” ….Web 2.0 is not merely tools or fancy looks, it is another way of producing and sharing information and new web tools facilitate that. It is not only simplicity, it is participation. PubMed has changed it looks, but it is not an interactive platform, where you can add or exchange information.

Well anyway, I probably didn’t succeed to explain in just a few sentences what Web 2.0 is and what it isn’t. For those that are unfamiliar with Web 2.0 and/or how it changes Medicine, I highly recommend the following presentation by Bertalan Mesko (of ScienceRoll and Webicina), who explains in a clear and nontechnical way what it is all about.

By the way Bertalan is a finalist with ScienceRoll in the 2009 Medical Weblog Awards (category Best Medical Technologies/Informatics Weblog). He could surely use your vote. (here you can vote in this category). You can see all Finalist here.

Medlibs Round 1.8 at Highlight Health

14 11 2009

For those that haven’t yet seen it:

The MedLib’s Round, the monthly blog carnival that highlights some of the best writing on medical librarianship, encompassing all stages in the publication and dissemination of medical information: writing, publishing, searching, citing, managing and social networking is up at Highlight Health (link).

The theme of this incredible 8th edition is: Finding Credible Health Information Online.

Walter Jessen introduces the round as follows:

There’s a revolution occurring on the Web: those “authoritative” articles written on traditional, static websites are being replaced with blogs, wikis and online social networks. In the sphere of health, medicine and information technology, this “real-time Web” consists of many who are experts in the field; these are their posts listed below.
In the digital age, these are the characteristics of new media: recent, relevant, reachable and reliable.

Subjects: “Searching the Web for health information”, “Biomedical research”, “Web 2.0 tools”, “PubMed Redesigned” and “Social media and participatory medicine” with contributions of Women’s Health News, Our Bodies Our Blog [@rachel_w]* Emerging Technologies Librarian [@pfanderson] Musings of a Distractible Mind [@doc_rob] Laika’s MedLibLog [@ericrumsey, Janet Wale, @Laikas], Significant Science [@hleman], Websearch Guide Internet News [Gwen Harris], Alisha764’s Blog [@alisha764] Next Generation Science [@NextGenScience], Dr Shock MD Ph [@DrShock], Life in the Fast Lane [@sandnsurf], Knowledge beyond words [@novoseek on Twitter], Eagle Dawg Blog [@eagledawg], The Search Principle blog [@giustini], Krafty Librarian [@Krafty], Dose of Digital [@jonmrich], [@SusannahFox] and Highlight HEALTH [@HighlightHEALTH].

Walter Jessen [wjjessen] concluded the blog carnival with a great presentation of Kevin Clauson [@kevinclauson] on the role of Facebook and Twitter in pharmacy and the development of participatory medicine. Since I intended to show this presentation anyway, I might as well place it here 😉 :

A Personalized Twitter Times: useful to others too.

13 10 2009

Yesterday I posted my “Introduction to Medicine 2.0” presentation on this blog and on Slideshare (where it is currently featured at their homepage).
Looking back I think that half of the participants found the Twitter part (and the way it is interwoven with other Web 2.0 tools) the most interesting, whereas this was the part where the other half was beginning to gaze. Later, Chris said that it should be no surprise that people not used to such a tool as Tweetdeck think: “What the hack is that, all those columns, with @, RT, names and links?” – it seems meaningless and such a waste of time. No matter what you tell them.

Today I received my personalized Twitter Times, which is constructed of blogposts that are most popular (most tweeted about) by my friends -the people whose ideas and interest I share on Twitter-. I find it a really neat overview of -indeed- very interesting posts. Certainly useful when a congress doesn’t allow me to follow tweets: I can read my newspaper late at night instead.

The Twitter Times is useful to other Tweople too, because they can find like-minded people they didn’t know by then.

Furthermore,  it might be useful for absolute beginners who don’t grasp the meaning of Twitter. Such a Twitter Times offers a far better overview and reads much more easily than tweets on Tweetdeck, which barely seem useful without their context.

Perhaps The Twitter Times could convince these skeptics to use Twitter as well. Or would they rather be inclined to say: “Thank you for the trouble, I rather read yours”….

Here is my real life personal ” Twitter Times” (and here is the PDF of Todays Twitter Times)

Cochrane 2.0 Workshop at the Cochrane Colloquium #CC2009

12 10 2009

Today Chris Mavergames and I held a workshop at the Cochrane Colloquium, entitled:  Web 2.0 for Cochrane (see previous post and abstract of the workshop)

First I gave an introduction into Medicine 2.0 and (thus) Web 2.0. Chris, Web Operations Manager and Information Architect of the Cochrane Collaboration, talked more about which Web 2.0 tools were already used by the Cochrane Collaboration and which Web 2.0 might be useful as such.

We had half an hour for discussion which was easily filled. There was no doubt about the usefulness of Web 2.0 for the Cochrane in this group. Therefore, there was ample room for discussing technical aspects, like:

  • Can you load your RSS feed of a PubMed search in Reference Manager? (According to Chris you can)
  • How can you deal with this lot of information (by following a specific subject, or not too much people – not many updates on a daily basis; you don’t have to follow it all, just pick up the headlines, when you can)
  • Are you involved in a Wiki that is successful? (it appears very difficult to involve people)
  • What happens if people comment or upload picture on facebook (of the Cochrane collaboration) in an appropriate way (Chris: didn’t happen, but you have to check and remove them)
  • How do you follow tweets (we showed Tweetdeckhashtags # and #followfridays)
  • What is the worst thing that happened to you (regarding web 2.0)? Chris and I thought a long time. Chris: that I revealed something that wasn’t officially public yet (though appeared to be o.k.). Me: spam (but I remove it/don’t approve it).
    Later I remembered two better (worse) examples, like the “Clinical Reader” social misbehaviour, a good example of how “branding” should not be done, and sites that publish top 50 and 100 list of bloggers just to get more traffic to their spam websites

Below is my presentation on Slideshare.

The (awful) green blackgound color indicates I went “live” on the web. As a reminder of what I did, I included some screendumps.

The current workshop was just meant to introduce and discuss Medicine 2.0 and Cochrane 2.0.

I hope we have a vivid discussion Wednesday when the plenary lectures deal with Cochrane 2.0.

The answers to my question on Twitter

  1. Why Web 2.0 is useful? (or not)
  2. Why we need Cochrane 2.0? (or not)

can be found on Visibletweets (temporary) and saved as: (permanent selection).

I think it would be good when these points are taken into account during the Cochrane 2.0 plenary discussions.

This week I will blog from…..

10 10 2009

35167809 singapore colloquiumPicture taken by Chris Mavergames

Chris and I will facilitate a web 2.0 workshop for the Cochrane (see here, for all workshops see here).
The entire program can be viewed at the Cochrane Colloquium site.

Chris Mavergames, Web Operations Manager and Information Architect of the Cochrane Collaboration will also give a plenary presentation entitled:
Cochrane for the Twitter generation:
inserting ourselves into the ‘conversation

The session has the promising title: The Cochrane Library – brave new world?

Here is the introductory text of the session:

The Cochrane Collaboration is not unique in facing a considerable challenge to the way it packages and disseminates healthcare information. The proliferation of communication platforms and social networking sites provides opportunities to reach new audiences, but how far can or should the Collaboration go in embracing these new media? In this session we hear from speakers who are at the heart of the discussions about The Cochrane Library’s future direction, including the Library’s Editor in Chief. We finish the session with reflections on the week’s discussions with respect to the Strategic Review (…)

Request (for the workshop, not the plenary session):
If you ‘re on Twitter, could you please tell the participants of the (small) web 2.0 workshop  your opinion on the following, using the hashtag #CC20.

  1. Why Web 2.0 is useful? (or not)
  2. Why we need Cochrane 2.0? (or not)

An example of such an answer (from @Berci):

#CC20 Web 2.0 opens up the world and eases communication. Cochrane 2.0 is needed bc such an important database should have a modern platform

If you don’t have Twitter you can add your comment here and I will post it for you (if you leave a name).

Thanks for all who have contributed so far.


*this is only for our small-scaled workshop, I propose to use #CC2009 for the conference itself.

The Trouble with Wikipedia as a Source for Medical Information

14 09 2009

This post was chosen as an Editor's Selection for

Do you ever use Wikipedia? I do and so do many other people. It is for free, easy to use, and covers many subjects.

But do you ever use Wikipedia to look up scientific or medical information? Probably everyone does so once in a while. Dave Munger (Researchblogging) concluded a discussion on Twitter as follows:

Logo of the English Wikipedia
Image via Wikipedia

“Wikipedia’s information quality is better than any encyclopedia, online or off. And, yes, it’s also easy to use”.

Wikipedia is an admirable initiative. It is a large online collaborative, multilingual encyclopedia written by contributors around the world.
But the key question is whether you can rely on Wikipedia as the sole source for medical, scientific or even popular information.

Well, you simply can’t and here are a few examples/findings to substantiate this point.



When you search  for diabetes in Google (EN), Wikipedia’s entry about diabetes ranks second, below the American Diabetes Association Home Page. A recent study published in the J Am Med Inform Assoc [1] confirms what you would expect: that the English Wikipedia is a prominent source of online health information. Wikipedia ranked among the first ten results in more than 70% of search engines and health-keywords tested, and outranked other sources in case of rare disease-related keywords. Wikipedia’s articles were viewed more frequently than the corresponding MedlinePlus Topic pages. This corroborates another study that can be downloaded from the internet here [10]. This study by Envision Solutions, LLC, licensed under the Creative Commons License, concluded that the exposure of Internet user’s to health-related user-generated media (UGM) is significant, Wikipedia being the most reference resource on Google and Yahoo.

The following (also from, from 2007 [10]) illustrates the impact of this finding:

According to the Pew Internet & American Life Project*, 10 million US adults search online for information on health each day [1]. Most (66%) begin their research on a search engine like Yahoo or Google. In addition, Americans are saying that the information they find on the Internet is having an impact. According to Pew, “53% of health seekers report that their most recent health information session [influenced] how they take care of themselves or care for someone else.” In addition, 56% say the information they find online has boosted their confidence in their healthcare decision-making abilities.

And according to an update from the Pew Internet & American Life Project (2009) [11]:

In 2000, 46% of American adults had access to the internet, 5% of U.S. households had broadband connections, and 25% of American adults looked online for health information. Now, 74% of American adults go online, 57% of American households have broadband connections, and 61% of adults look online for health information.

Thus a lot of people look online for health care questions and are more inclined to use highly ranked sources.
This is not unique for Health topics but is a general phenomenon, i.e. see this mini-study performed by a curious individual: 96.6% of Wikipedia Pages Rank in Google’s Top 10 [12]. The extreme high traffic to Wikipedia due to search referrals has  even been been denounced by SEO-people (see here) [13]: if you type “holiday” Wikipedia provides little value when ranking in the top 10: everybody knows what a holiday is 😉

Medical students use it too.

A nightmare for most educators in the curriculum is that students rely on UGM or Web 2.0 sites as a source  of medical information. Just walk along medical students as they work behind their computers and take a quick glance at the pages they are consulting. These webpages often belong to the above category.

AnneMarie Cunningham, GP and Clinical Lecturer in the UK, did a little informal “survey” on the subject. She asked 31 first year medical students about their early clinical attachments in primary and secondary care and summerized the results on her blog Wishful Thinking in Medical Education [14]. By far and away Wikipedia was the most common choice to look up unfamiliar clinical topics.


‘Many students said I know I shouldn’t but….’ and then qualified that they used Wikipedia first because it was easy to understand, they felt it was reasonably reliable, and accessible. One student used it to search directly from her phone when on placement..

50% of the doctors use it!

But these are only medical students. Practicing doctors won’t use Wikipedia to solve their clinical questions, because they know where to find reliable medical information.


The New Scientist cites a report [15] of US healthcare consultancy Manhattan Research (April 2009), stating that that 50 percent of the doctors turn to Wikipedia for medical information.

A recent qualitative study published in Int J Med Inform [2] examined the “Web 2.0” use by 35 junior physicians in the UK. Diaries and interviews encompassing 177 days of internet use or 444 search incidents, analyzed via thematic analysis. Although concepts are loosely defined (Web 2.0, internet and UMG are not properly defined, i.e. Google is seen as a web 2.0 tool (!) [see Annemarie’s critical review [16] the results clearly show that 89% of these young physicians use at least one “Web 2.0 tool” (including Google!) in their medical practice, with 80% (28/35) reporting the use of wikis. The visit of wiki’s is largely accounted for by visits to Wikipedia: this was the second most commonly visited site, used in 26% (115/44) of cases and by 70% (25/35) of all physicians. Notably, only one respondent made regular contribution to a medical wiki site.

The main motivation for using the Internet for information seeking was the accessibility and ease of use over other tools (like textbooks), the uptodateness, the broad coverage and the extras such as interactive immages. On the other hand most clinicians realized that there was a limitation in the quality or usefulness of information found. It is reassuring that most doctors used UGM like Wikipedia for background or open questions, to fulfill the need for more in depth knowledge on a subject, or to find information for patients, not for immediate solving of clinical questions.

The Int J Med Inform article has been widely covered by blogs: i.e. see Wishful Thinking in Medical Education [16], Dr Shock, MD, PhD [17], Life in the Fast Lane [18], Clinical Cases and Images Blog [19] and Scienceroll [20].

Apparently some doctors also heavily rely on Wikipedia that they refer to Wikipedia articles in publications (see the Int. J Cardiol. PubMed [3] abstract below)!!

Whether the common use of Wikipedia by e-patient, medical students and doctors is disadvantageous depends on the quality and the trustworthiness of the Wikipedia articles, and that is in its turn dependent on who writes the articles.

Basically, the strength of Wikipedia is it weakness: anyone can write anything on any subject, and anyone can edit it, anonymously.

Negative aspects include its coverage (choice of subjects but also the depth of coverage), the “overlinking”, the sometimes frustating interactions between authors and editors, regularly leading to (often polite) “revision wars“, but above all the lack of ‘expert’ authors or peer review. This may result in incomplete, wrong or distorted information.

Positive aspects are its accessibility, currency, availability in many languages, and the collective “authorship” (which is an admirable concept).

The following humorist video shows how the wisdom of the crowds can lead to chaos, incorrect and variable information.

SCOPE AND ACCURACY (What has been covered, how deep and how good) :

Too much, too little, too ….

With respect to its coverage one study in the Journal of Computer-Mediated Communication (2008) [4] concludes:

Differences in the interests and attention of Wikipedia’s editors mean that some areas, in the traditional sciences, for example, are better covered than others. (…)
Overall, we found that the degree to which Wikipedia is lacking depends heavily on one’s perspective. Even in the least covered areas, because of its sheer size, Wikipedia does well, but since a collection that is meant to represent general knowledge is likely to be judged by the areas in which it is weakest, it is important to identify these areas and determine why they are not more fully elaborated. It cannot be a coincidence that two areas that are particularly lacking on Wikipedia—law and medicine—are also the purview of licensed experts.

It is not unexpected though that Wikipedia’s topical coverage is driven by the interests of its users.

Sometimes data are added to Wikipedia, that are in itself correct, but controversial. Recently, Wikipedia published the 10 inkblots (Scienceroll, [21]) of the Rorschach test, along with common responses for each. This had led to complaints by Psychologists , who argue that the site is jeopardizing one of the oldest continuously used psychological assessment tests (NY Times [22]).

The actual coverage of medical subjects may vary greatly. In one study [5], abstract-format, 2007) Wikipedia entries were screened for the most commonly performed inpatient surgical procedures in the U.S. Of the 39 procedures, 35 were indexed on Wikipedia. 85.7% of these articles were deemed appropriate for patients. All 35 articles presented accurate content, although only 62.9% (n=22) were free of critical omissions. Risks of the procedures were significantly underreported. There was a correlation between an entry’s quality and how often it was edited.

Wikipedia may even be less suitable for drug information questions, questions that one-third of all Internet health-seekers search for. A study in Annals of Pharmacotherapy [6] comparing the scope, completeness, and accuracy of drug information in Wikipedia to a free, online, traditionally edited database (Medscape Drug Reference [MDR]) showed that  Wikipedia answered significantly fewer drug information questions (40.0%) compared with MDR (82.5%; p < 0.001) and that Wikipedia answers were less complete. Although no factual errors were found, errors of omission were higher in Wikipedia (n = 48) than in MDR (n = 14). The authors did notice a marked improvement in Wikipedia over time. The authors conclude:

This study suggests that Wikipedia may be a useful point of engagement for consumers looking for drug information, but that it should be supplementary to, rather than the sole source of, drug information. This is due, in part, to our findings that Wikipedia has a more narrow scope, is less complete, and has more errors of omission versus the comparator database. Consumers relying on incomplete entries for drug information risk being ill-informed with respect to important safety features such as adverse drug events, contraindications, drug interactions, and use in pregnancy.
These errors of omission may prove to be a substantial and largely hidden danger associated with exclusive use of
user-edited drug information sources.

Alternatively, user-edited sites may serve as an effective means of disseminating drug information and are promising as a means of more actively involving consumers in their own care. However, health professionals should not use user-edited sites as authoritative sources in their clinical practice, nor should they recommend them to patients without knowing the limitations and providing sufficient additional information and counsel…

Not Evidence Based

German researches found [7], not surprisingly, that Wikipedia (as well as two major German statutory health insurances):

“…failed to meet relevant criteria, and key information such as the presentation of probabilities of success on patient-relevant outcomes, probabilities of unwanted effects, and unbiased risk communication was missing. On average items related to the objectives of interventions, the natural course of disease and treatment options were only rated as “partially fulfilled”. (..)  In addition, the Wikipedia information tended to achieve lower comprehensibility. In conclusion(..) Wikipedia (..) does not meet important criteria of evidence-based patient and consumer information though…”

Wrong, misleading, inaccurate

All above studies point at the incompleteness of Wikipedia. Even more serious is the fact that some of the Wikipedia addings are wrong or misleading. Sometimes on purpose. The 15 biggest wikipedia blunders [23] include the death announcements of Ted Kennedy (when he was still alive),  Robert Byrd and others. Almost hilarious are the real time Wikipedia revisions after the presumed death of Kennedy and the death of Ken Lay (suicide, murde, heart attack? [24).

In the field of medicine, several drug companies have been caught altering Wikipedia entries. The first drug company messing with Wikipedia was AstraZeneca. References claiming that Seroquel allegedly made teenagers “more likely to think about harming or killing themselves” were deleted by a user of a computer registered to the drug company [25], according to Times [26]. Employees of Abbott Laboratories have also been altering entries to Wikipedia to “eliminate information questioning the safety of its top-selling drugs.”(See WSJ-blog [27] , [28], and recently Kevin MD[29])

These are “straightforward” examples of fraudulent material. But sometimes the Wikipedia articles are more subtly colored by positive or negative bias.

Take for instance the English entry on Evidence Based Medicine (in fact the reason why I started this post). Totally open-minded I checked the entry, which was automatically generated in one of my posts by Zemanta. First I was surprised by the definition of EBM:

Evidence-based medicine (EBM) aims to apply the best available evidence gained from the scientific method to medical decision making. It seeks to assess the quality of evidence of the risks and benefits of treatments (including lack of treatment).

instead of the usually cited Sacket-definition (this is only cited at the end of the paper):

“the practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research”

In short, the whole article lacks cohesion: the definitions of EBM are not correct, there is too much emphasis on not directly relevant information (4 ways to grade the evidence and 3 statistical measures), the limitations are overemphasized (cf. chapter 7 with 6 in the Figure below) and put out of perspective.

Apparently this has also been noted by Wikipedia, because there is a notice on the Evidence Based Medicine Page saying:

This article has been nominated to be checked for its neutrality. Discussion of this nomination can be found on the talk page. (May 2009)

9-9-2009 9-55-04 wikipedia EBM start smal

Much to my surprise the article had been written by Mr-Natural-Health, who’s account seems not to be in use since 2004  and who is currently active as User:John Gohde. Mr Natural Health is a member of WikiProject Alternative medicine.

Now why in earth would some advocate of CAM write the Wikipedia EBM-entry? I can think of 4 (not mutually exclusive) reasons:

  1. When you’re an EBM-nonbeliever or opponent this is THE chance to misinform readers about EBM (to the advantage of CAM).
  2. The author was invited to write this entry.
  3. No EBM-specialist or epidemiologist is willing to write the entry, or to write for Wikipedia in general (perhaps because they find Wikipedia lacks trustworthiness?)
  4. EBM specialists/epidemiologists are not “allowed”/hindered to make major amendments to the text, let alone rewrite it.

According to Mr Naturopath point 2 is THE reason he wrote this article. Now the next question is “exactly by whom was he invited?” But the TALK-page reveals that Mr Naturapath makes it a tough job for other, better qualified writers, to edit the page (point 4). To see how difficult it is for someone to re-edit a page, please see the TALK-page. In fact, one look at this page discourages me from ever trying to make some amendments to any Wikpedia text.


Changes to Wikipedia’s organization

Wikipedia has long grasped that its Achilles heel is the free editability (see for instance this interview with Wikipedia’s founder [30]). Therefore, “WikiProjects” was initiated to help coordinate and organize the writing and editing of articles on a certain topic, as well as “Citizendium” which is an English-language wiki-based free encyclopedia project aimed to improve the Wikipedia model by providing a “reliable” encyclopedia. “It hopes to achieve this by requiring all contributors to use their real names, by strictly moderating the project for unprofessional behavior, by providing what it calls “gentle expert oversight” of everyday contributors, and also through its “approved articles,” which have undergone a form of peer-review by credentialed topic experts and are closed to real-time editing.”

Starting this fall Wikipedia will launch an optional feature called “WikiTrust” will color code every word of the encyclopedia based on the reliability of its author and the length of time it has persisted on the page: Text from questionable sources starts out with a bright orange background, while text from trusted authors gets a lighter shade.

9-9-2009 15-25-36 wikipedia wikiproject medicine

The Wikipedia EBM article is within the scope of these two projects, and this is good news. However, Wikipedia still clings to the idea that: “Everyone is welcome to join in this endeavor (regardless of medical qualifications!).” In my opinion, it would be better if Wikipedia gave precedence to experts instead of hobbyists/ people from another field, because the former can be expected to know what they are talking about. It is quite off-putting for experts to contribute. See this shout-out:

Who are these so-called experts who will qualify material? From what I’ve seen so far, being an academic expert in a particular field hardly protects one from edit wars–Julie and 172 are two primary examples of this. Meanwhile, the only qualification I have seen so far is that they have a B.A. Gimme a friggin’ break! (and before I get accused of academic elitism, I make it known that I dropped out of college and spend an inordinate amount of time at work correcting the BS from the BAs, MAs, and PhDs).

While anyone can still edit entries, the site is testing pages that require changes to be approved by an experienced Wikipedia editor before they show up, the so called Flagged protection and patrolled revisions. (see Wikimedia) This proposal is only for articles that are currently under normal mechanisms of protection (i.e. the Obama-article cannot be edited by a newcomer).

Although this seems logic, it is questionable whether “experienced” editors are per definition better qualified than newcomers. A recent interesting analysis of the Augmented Social Cognition group [31], (cited in the Guardian [32]) shows a slowdown in growth of Wikipedia activity, with the activity slightly declining in all classes of editors except for the highest-frequency class of editors (1000+ edits). Here is an increase in their monthly edits.

In addition the study shows growing resistance from the Wikipedia community to new content. The total percentage of reverted edits increased steadily over the years, but more interestingly, low-frequency or occasional editors experienced a visibly greater resistance compared to high-frequency editors . Together this points at a growing resistance from the Wikipedia community to new content, especially when the edits come from occasional editors.

This is more or less in line with an earlier finding [9] showing that Wikipedia members feel more comfortable expressing themselves on the net than off-line and scored lower on agreeableness and openness compared to non-Wikipedians, a finding that was interpreted as consistent with the possibility that contributing to Wikipedia serves mainly egocentric motives.

Encouraging students, doctors and scientists (provisional)

One way of improving content, is to encourage experts to write. To achieve that the information on Wikipedia is of the highest quality and up-to-date, the NIH is encouraging its scientists and science writers to edit and even initiate Wikipedia articles in their fields [36]. It joined with the Wikimedia Foundation, to host  a training session on the tools and rules of wiki culture, at NIH headquarters in Bethesda.

A less noncommital approach is the demand to “Publish in Wikipedia or perish”, as described in Nature News [9]. Anyone submitting to a section of the journal RNA Biology will, in the future, be required to also submit a Wikipedia page that summarizes the work. The journal will then peer review the page before publishing it in Wikipedia.” The project is described in detail here [10] and the wiki can be viewed here

Wiki’s for experts.

One possible solution is that scientist and medica experts contribute to wiki’s other than the Wikipedia. One such wiki is the wiki-surgery [5]. PubDrugRxWiki , WikiProteins [11] and Gene Wiki [12] are other examples. In general, scientists are more inclined to contribute to these specialists wiki’s, that have oversight and formal contributions by fellow practitioners (this is also true for the RNA-wiki)

A medical Wikipedia

Yet another solution is a medical wikipedia, such as Ganfyd or Medpedia . Ganfyd is written by medical professionals. To qualify to edit or contribute to the main content of Medpedia approved editors must have an M.D., D.O., or Ph.D. in a biomedical field. Others, however, may contribute by writing in suggestions for changes to the site using the “Make a suggestion” link at the top of each page. Suggestions are reviewed by approved editors. Whether these medical wikipedias will succeed will depend on the input of experts and their popularity: to what extent will they be consulted by people with health questions?

I would like to end with a quote from Berci during twitterview (link in Wikipedia):

Twitter’s #FollowFriday #FF – Over the Top. Literally

11 09 2009

Last Update: Sunday (2009-13-09), text added in blue

The Twittermeme #FollowFriday (or #FF) was started January this year by Micah Baldwin (@micah) with one single Tweet: I am starting Follow Fridays. Every Friday, suggest a person to follow, and everyone follow him/her. Today its @fancyjeffrey & @w1redone.”

10-9-2009 23-33-49 followfriday

A friend of Micah suggested to add the hashtag (a community driven tag) #FollowFriday to the tweet, some other friends helped to spread the word and a tweetmeme was born: now, all over the world #FollowFriday is a Twitter “trending topic” on Fridays (see Mashable)

The concept of FollowFriday is that every Friday you recommend a few people to your Twitter-followers. For at least 2 reasons:

  1. it is a way to acknowledge those particular people
  2. it is a very efficient way for your followers to find other interesting Twitter people

Ideally (at least IMHO) the #FollowFriday tweets (message of 140 characters or less):

  • should consist of:
    • the hashtag #FollowFriday,  #FF or both
    • 1-3 names of people you would like to recommend (the tweet should not start with their names, because otherwise only the recommend person himself and your mutual friends will be able to read the tweet, -this doesn’t make much sense)
    • a short explanation why you recommend him/her.
  • are tweeted on Fridays
  • are more or less unique (just one or two tweets, not dozens in a row)
  • should only recommend the best people in a particular field

Two examples, one by me and one by @jpardopardo (it was my one and only #FF recommendation in two weeks)

  1. Laika (Jacqueline)
    laikas My #followfriday goes to @aarontay , a techy librarian from Singapore. Has many tips as a tweeter and a blogger #ff #fb
  2. Jordi Pardo Pardo
    jpardopardo #followfriday Cochrane tweets you can not miss: @cochranecollab @radagabriel @MESOttawa @laikas @TSC_OH @DavidTovey

this quote was brought to you by quoteurl

In these examples the hashtag #FollowFriday is followed by one or several names with the reason one should follow the person.

The general format thus would be:

#followfriday #FF @username Reason why you should follow him/her, area of interest, Their website URL, if applicable

If my followers see that I consider @aarontay a great techy librarian having a lot of good tips, they might find it worth while 2 check him by clicking @aarontay or the link to his blog If they go to his Twitter homepage and  find his tweets awesome, than they might decide to start following him.

If you’re interested in the Cochrane Collaboration, then you might try the tweople that are recommended by @jpardopardo. It takes somewhat more time, however, to check all 6 people, but it may yield some interesting new people to follow.

Thus, in principle #FollowFriday is a great tool to find other interesting people, BUT…

…suppose you’re following someone that tweets all this (x 3-5 times) every Friday?

29-8-2009 15-19-18 #followfriday

I don’t follow this person (name not shown), but if I did, these #FollowFridays are really meaningless. I don’t know why I should follow the “suggested” people, nor do I want to try all the links. Furthermore if someone produces 10 or more of these kinds of tweets (those people exist!), my twitter account gets clogged with useless clutter. Its worse than an inbox full with spam.

But some people are even worse. They not only tweet a huge amount of meaningless FollowFridays, they also retweet (RT) the FollowFridays in which they are included to let the world know how popular they are (I can’t think of any other reason than that they want to show off).

29-8-2009 15-22-28 ff dr sg

And it is counterproductive….

Instead of following the recommended people I will unfollow those kind of FollowFridaying people (at the end).

I’m not a CEO or a marketing woman. I don’t want 10000 people to follow me, and even less so do I want to follow 10.000 people back.

I only desire to follow interesting people with a high signal to noise ratio of tweets in a manageable way.

I always thought that I was exceptional in thinking like this, but last two weeks several of my Twitter friends started to talk about the downside of FollowFridays. And when I Googled, o dear, the whole Twitterverse seemed to have written about it. (glad I Googled after I had almost finished this post)

  1. Ves Dimov, M.D.
    DrVes I don’t participate in “Follow Friday” (any day is good to recommend somebody) but @Dr_Steve_Ponder offers great diabetes info as Dr/patient
  2. David Bradley
    sciencebase I think it’s time to abandon #FollowFriday as a twitter meme, unless we can make it more useful and effective.
  3. novo|seek
    novoseek agree / RT @sciencebase: I think it’s time to abandon #FollowFriday as a twitter meme, unless we can make it more useful and effective.
  4. Laika (Jacqueline)
    laikas RT @sciencebase: think it’s time 2 abandon #FollowFriday as a twitter meme, unless we can make it more useful/effective. wouldn’t agree more
  5. Walter van den Broek
    DrShock RT @laikas: RT @sciencebase: think it’s time 2 abandon #FollowFriday what about #rec?

Oh and here is another one today (13-09)
pfanderson @laikas @wichor Yeah, I really hate it on Follow Friday when folks fill up a whole page nothing but people’s names. from web in reply to laikas

SO WHAT ARE THE SOLUTIONS? (blue added after publication)


  1. Abandon FollowFriday
  2. Just recommend anyone (special) whenever you like (DrVes , DrShock),
  3. @MarilynMann: “What I do find useful is when someone joins twitter and people tweet “please welcome ___ to twitter,” which can be done any day of the week”
  4. @sciencebase: “RT is the much better way to show fellow twitters that you care. If you’re RT’ing their tweets then you’re demonstrating that what they’re saying bears repeating, so recommending them indirectly…”
  5. @philbaumann ‘s tip mentioned by @problogger in the same post Mark tweets from people you want to recommend on FollowFriday by favoriting them and tweet the URL of your favorites page (i.e., see the URL of Philbaumann’s Favorites page).
  6. Share Groups of Twitter Users in One Click with TweepML (Mashable) – here are some lists from which you can choose:, including a top librarianlist. Of course there are already many lists and directories around, but the good thing is that you can personalize your own top groups and that another person can add anyone from that list by simple clicking.
  7. Use #MrTweet Instead of #FollowFriday, send your weekly recommendation there, get an overview of the most awesome people according to your friends and get recommended yourselves (see bkmacdaddy). [added 2009-09-02]


  8. Use FollowFriday sparingly and wisely, i.e. as described above. In fact the founder of FollowFriday proposes similar rules.
  9. Mention a series of people on Twitter and tell why they’re great people on your blog there is more room there (sucomments)
  10. @problogger: (on his blog your tweets throughout the day via scheduling services like Tweetlater (currently rebranding themselves as SocialOomph, Futuretweet or Hootsuite” (while taking care of the twitteretiquette, see above).
  11. Matt Stratton proposes to use the hashtag fussy-follow-friday, to discrimate good tweets from bad ones.
  12. Maija Haavisto, again on “ask others for recommendations (such as “female sports bloggers” ..), either as a normal tweet or by posing a question to someone. They reply with names of Twitter users – preceding the initial @ with a period or something else, if they want others to see their recommendations. All tweets should be tagged with #ff or #followfriday, of course.

    EXTRA TIP TO KEEP YOUR Followfriday-recommendations

  13. Perform a Twittersearch with (your @twittername  OR your twittername) (#followfriday OR #ff OR followfriday) and take an RSS-feed to that search. You see your recommendations and who has recommended you.
    Thus my search looks like
    (laikas OR @laikas)(#followfriday OR #ff OR followfriday) (and you can also add “friday”)

To add fussy-follow-friday to the follow friday tweet [10] seems unnecessarily complex to me. Asking others for recommendations [11] is a good suggestion, but I don’t see me applying that approach each Friday. I would (and already do) use this approach on selected occasions. Why not just use FollowFriday as it was meant to be used: recommend one or two people once a week [3]. I still like the idea. Contrary to marketing people and strategists, I’m already happy and honored when I’m FollowFridayed: for me it doesn’t have to lead to tons of followers (for others this is the main goal). In my case it has lead to some new, great twitterfriends. Quality is more important to me than quantity. I’ve  “met” some new interesting people, who I might not have met otherwise.

Option 2, 3 and 4 also seem very sensible to me. I share the mild) critique of @problogger regarding 5: “Not every tweet I Favorite comes from someone I necessarily want to recommend and favorites are not necessarily tweets planned on sharing. But people not using favorites often might find this an excellent option.”

6 seems more of an adjunct, nice tool, but less personal.

What do you think?

(Solutions may be added to the above list)

suggest a list of people they followed whom they believed others would also enjoy
