It was the perfect storm: As social media sites were gaining in popularity, health care was becoming more expensive and doctors’ time was becoming more finite and valuable.

It was only a matter of time before patients and their families began turning to health care social networks for medical information and even emotional support.

The Wall Street Journal discusses the trend in an insight article:

Online health sites have been booming in the past five years … Many of the sites have recently experienced heavy traffic from users seeking information on the H1N1 virus. Officials of the Health 2.0 Conference, which tracks the industry, estimate that the number of such sites climbed to nearly 500 from about 35 four years ago.
