....but that's not at all the focus nor the point of Facebook. It's networking. If some people use it to "hook up", fine, but then, people use email for that too, as well as classified ad sites, etc. Maybe you didn't mean it as literally as you stated it, but if you did, you're way off base. Now, if you've checked it out and it doesn't interest you, fine, but don't label it as being about something other than its intended purpose.
Yes, I've checked out Facebook ... and My Space .... and quite frankly ..... don't want to be apart of either. If I wanna e-mail 5, 10, or 50 people .... I do so .... and I don't need all the "Mybookspaceface" hoopla and horse and pony show to go along with it.
I'm 40 and have loved using Facebook (and prior to its decline, MySpace) to re-connect with old friends, keep up with new ones, family, etc. I organized my family's gathering for my 40th birthday (yeah, kinda cheesy, but I didn't wanna be surprised with something corny) via Facebook, and it was 100 times easier than making a bajillion phone calls.
And that's fine. If it works for you ... more power to ya ....
