I joined Facebook this afternoon. I'm not sure what I've done, or really what it is, but so far I have 7 "friends." These are mostly people from my days in San Francisco. We were a pretty tightly knit group, though not a small group. Some I have kept in touch with, and others it is great to reconnect with. David joined about a week ago and has reconnected with people from his Catholic school days up until the present. My sister has been on it for a while too.
I'm just trying to figure out how this works and am looking forward to seeing some "blasts from the past" send me an invitation to be their "friend." After that, I'm really not sure what is supposed to happen. I'll let you know how it goes!
