The most famous article ever written about web 2.0 and medicine belongs to Dean Giustini (UBC biomedical branch librarian) who now made an other big step in this special field. Check out the new article (Web 3.0 and medicine) on British Medical Journal online.
A great honor for me is that Scienceroll has been used as a reference:
Social software enthusiasts may well find that the new web will be fertile ground for the creation of knowledge. Although already popular, wikis may well serve as platforms for the exploration of web 3.0. One innovative wiki—Wikiproteins—is already using semantic technologies. In contrast to other wikis, Wikiproteins imports data mined from several of the world’s leading biomedical databases, such as PubMed, UniProt, and the National Library of Medicine. Its integrated entries are a useful combination of genetic information and scientific literature. Notably, the confluence of databases in Wikiproteins yields more than two million factual associations for data mining and over five billion associated pairs.9
