For those health searchers who do turn to social media content and communities, online forums and message boards such as Yahoo! and Google Groups and [email protected] are the most often used resource, at 38%, followed closely by Wikipedia, at 30%, according to iCrossing. Social networks, both general and health-specific, can be considered a secondary resource in these instances (used by 14% of respondents), while streaming or downloadable video and audio have yet to enter the mainstream.
