Are you an average social networker? If so, you have about 229 Facebook friends, according to a recent Pew study, Social Networking Sites and Our Lives.

Just who are these “friends?” The average list includes:

  • High school friends: 22 percent
  • Extended family:12 percent
  • Co-workers:10 percent
  • College friends: 9 percent
  • Immediate family: 8 percent
  • Voluntary groups: 7 percent
  • Neighbors: 2 percent

And chances are you trust these people, and people in general. The study found that “a Facebook user who uses the site multiple times per day is 43 percent more likely than other Internet users and more than three times as likely as non-Internet users to feel that most people can be trusted.”
