what’s the definition of Health2.0?

Our definition is currently focusing on user-generated aspects of Web2.0 within health care but not directly interacting with the mainstream health care system. That means, a) search, b) communities, c) tools for individual and group consumer use. But clearly there are blurring boundaries between all these, and the question of connecting Health2.0 user-generated content to the wider health care system—which hasn't exactly adopted Web1.0 with a flourish yet—is coming into closer focus as more clinicians and organizations start to use these technologies to communicate with consumers.

Health 2.0 (as well as the closely related concept of Medicine 2.0) are terms representing the possibilities between health care, eHealth and Web 2.0, and has come into use after a recent spate of articles in newspapers, and by Physicians and Medical Librarians.A concise definition of Health 2.0 is the use of a specific set of Web tools (blogs, Podcasts, tagging, search, wikis, etc) by actors in health care including doctors, patients, and scientists, using principles of open source and generation of content by users, and the power of networks in order to personalize health care, collaborate, and promote health education. A possible explanation for the reason that Health has generated its own "2.0" term are its applications across health care in general, and in particular it potential in public health promotion. One author describes the potential as "limitless."
