Pew Research Center on Social Isolation and New Technology

Link to November 4 Pew Internet & American Life Report.

Excerpt: This Pew Internet Personal Networks and Community survey finds that Americans are not as isolated as has been previously reported.

And, when we examine people's full personal network -- their strong and weak ties -- internet use in general, and use of social networking services such as Facebook in particular, are associated with more diverse social networks.
