Nothing new here. Ozmosis is based on the now-old concept of physician networking website, with features like knowledge exchange, journal club, cases, alerts, news etc. Looking at dataopedia, they don’t have much traction either (roughly 1K visitors per month).
Although I’d always like to write about novel ideas, exceptions like these are purely from a record-keeping perspective. I’m trying to get a rough list of how many different takes of social networking for clinical professionals are currently floating around on the web.
September 2010 Update: The website is no longer functional.
