I have unfriended most church people except those who are close, personal friends. The unpleasantness last Spring really opened my eyes to how Facebook can mark you in ways you don't anticipate. I also get random friend requests from ukulele people who, I think, see my activity on the UWC Facebook groups and things like that. I guess they figure if I'm a uke person I must also be a friend. I used to accept those, but have lately dumped most of them as well. My criteria now is that we must have a relationship that predates the Facebook friend request....
