Yes, but the difference is, I consider sites like facebook and myspace to be pure evil. Even more so than our beloved admin's cat, Saffron.
I agree that myspace is evil, but that's a combination of no more than three things:
1) most pages there look like throwup from a early-nineties HTML editor.
2) there's too many XxXcoreXxX cluetards.
3) it sucks
On the other hand, I find facebook to be pretty useful. Be conscious of who you add as a friend, stay away from the applications, and apply some sane privacy settings - presto. My family and real-life friends are scattered across Denmark, so it's a pretty convenient way of keeping in touch with people. I've gotten back in touch with people that I haven't seen for a while... and finally, it's so much easier being up-to-date with what happens (concerts, events, ...) in my city through "hive mind" of status updates and event invitations than having to check several other sites.
If I was the kind of person that called in sick to go drinking, I'd probably stay away from FaceBook... but I'm not and I don't
