I don't use FB for much personal contact, but as a member of a local rock band, it's been a wonderful tool. We send out "invites" every time we play a club. It gets people buzzing about the gig. It's also nice, as it saves us from having to buy webspace. No more sending out bulk emails with possibilities of losing them in spam folders. People post pictures of themselves at gigs, and it gives off a party vibe. There will probably be something else to come along, but FB is great for us at the moment.
