A detailed search of articles appearing in Pubmed on emerging and social technologies found the second most popular topic was virtual worlds. (The first topic was the broad "Web 2.0".) Virtual worlds in general and Second Life in particular are growing into a significant research area with increasing numbers of researchers devoting attention to this area. While we won't try to be comprehensive here in SLHealthy, we would be remiss if we didn't address this and direct people to some of the research available. Here you can find an RSS feed of recent research in this area. Check for additional links in the navigation sidebar on the left side of the screen for a selected bibliography and discussion topics of interest to our community.
