Laura Landro wrote this week in the Wall Street Journal about the extension of the online social networking phenomenon, e.g. My Space, to health care issues, such as diabetes. She notes a dedicated web site called Dailystrength.org. She also notes that the American Cancer Society and the U.S. Centers for Disease Control are using a social networking site call Second Life as a bully pulpit. I had never heard of Second Life until I read this article. Second Life is a site where you can live a second life as an avatar — over 2,000,000 users (not me). Landro reports that “The CDC has held some virtual health fairs on the Second Life Web site where visitors can learn about subjects like pandemic flu resources.” Creative.
