I still have a FB account and even check it every now and then.  I do find it depressing and I finally figured out why.  I don't want to know that much about the people I love or like.  Like my nephew.  Great kid, and will be a great adult.  However, I inevitably think less of him when I read his teenaged musings.  Who wouldn't?  I don't want to hear it.  We connect at a certain level, and FB breaches that connection.  I don't want to hear the things he says to girls or his buddies, or the guy who cut him off in traffic.  I like him a lot better when we have boundaries.
