Social network sites drawing older users

More than half the adult users of social networking sites such as Facebook and Twitter are older than 35, up from a third just two years ago, according to a new report by the Pew Research Center’s Internet and American Life Project.

The survey of 2,255 adults over 18 also found that use of social networking sites does not isolate users, as some have feared. Rather, users of Facebook, which is favored by 92 percent of those who engage in social networking, tend to be more trusting of others, have more close relationships, get more social support and engage more in politics than other people, the survey found.
