AskDrWiki Editorial Board
If you have been following the AskDrWiki threads around the blogosphere (David Rothman, Doctor Wiki, AMA News, etc.) you will know that the creators of AskDrWiki have instituted a detailed editorial policy to help ensure that accurate and quality medical information is posted.
Unlike many wiki and blog pages, editors on AskDrWiki are not anonymous and are identified with their name and degree. Now the Who is Dr Wiki Page not only lists the editors but it will also link to their resume or curriculum vitae. Examples: Kenny Civello MPH, MD and Brian Jefferson MD.
AskDrWiki is still a little subject heavy in Cardiology, however they are looking for editors in every specialty. For example the Biomedical Informatics section is currently empty, so if there are any librarians, physicians, medical information systems people who specialize in Biomedical Informatics, you might want to drop them an email and help contribute.
