I only joined FB because I heard a schoolfriend was trying to get in touch with me (my first big crush). Since she got to hear from me (probably a bit too much) and the fact she's a bit of an Xian fundie, it's stopped. Sad in a way, meh in another.
The weird thing is I got a whole bunch of befriend requests (or whatever they're called, from girls I went to primary school with. Why weird? Because I haven't seen these girls since 1970
! That's out there!
Oh, they chatter on, and are quite pleasant, but it's... I dunno. The people themselves, I stress, are okay, and it's kinda fun to be taken down Memory Lane and mugged. I think the whole way FB is set up with those silly bloody kidnap games and crap, is lame. Staying in touch with people is fine, I just wish there was a 'cool FB'
(So if you're a programmer, there's a market going begging! You can have that idea for free!)
Don't even think about Twitter.
