CPL 2.0 Is Facebook useful or a time-waster?

Is Facebook, for me, useful or a time-waster? Well, let's see. I am on Facebook so infrequently that whether or not I'm "wasting" time really doesn't matter too much one way or the other. Since the reason I have a Facebook page is primarily to be able to view my children's and my nieces' holiday photos, I would have to say that Facebook serves a useful purpose for me. However, sometimes it's a few months before I see a message some one has sent me. It can be a bit awkward responding so late! It is a social network, yet using it the way I do leaves me feeling that I've been a little anti-social, somehow.
