It's well-known that there's yet no common agreement amongst experts and participants about what Health 2.0 is, just look at the Health 2.0 wiki with its several competing and complementary definitions.
Recently we have become aware of "new" concept called eHealth 2.0. What's that? Sounds like the
illegitimate son of the relationship of eHealth and Health 2.0, somehow.
Do we really need another buzzword that includes things and concepts like electronic health records, telemedicine, consumer health informatics, health knowledge management, virtual healthcare teams, mHealth, m-Health, medical research using grids, or healthcare information systems? Old wine in new skins. But quiet tasty, though. Except for the reference list.
