​ The survey results reported here were undertaken to explore issues that have not been probed directly in that study and other related research on social isolation: the role of the internet and mobile phone in people's core social networks. This Pew Internet Personal Networks and Community survey finds that Americans are not as isolated as has been previously reported. People's use of the mobile phone and the internet is associated with larger and more diverse discussion networks. 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.
