A couple of years ago at one of my talks about using the Web for research and education, I was showing various sites and resources, including wikis (wiki being short for "what I know is") and the grand wiki of them all, Wikipedia. Initially Wikipedia was dismissed by many because they assumed that an online encyclopedia of user-generated information would never work. Critics claimed it was too unreliable and there would be no way to verify all the content. Indeed, there were initial reports of faulty information on the site. I admit that initially I had my doubts as well. But eventually it overcame its problems and now is one of the most widely accessed and trusted web sites in the world. It has become THE site for quick lookups of information on just about every topic imaginable in a multitude of languages. So wouldn't it be cool if there was a wiki for medicine? Well there is.
