Lots of friends, dood!
Heh. The only place you'll find me with 100 odd friends would be hi5, and even I admit that only 50 or something are actual, Real-Life friends. The others are sometimes people I know, but not that much of a friend though. hi5 did have my attention as I was able to get in contact with long-lost friends, so Facebook came too late for me. In fact, I think hi5 was the first one out there, as most of my close friends call social networks "hi5 imitators".
While I do believe you can have internet-based friends, that doesn't automatically mean "linked by a social network". Even with instant messaging or email, there are a lot of people that only send me crappy chain-mails and nothing else. Thats the reason my livejournal has about 3 friends, my MSN spaces thingy has about 8 and only the hi5 one has "a lot". I don't really link anyone but actual friends now, I just grew tired of getting craploads of chainmails because that is someone's braindead idea of "keeping in touch".
If I want to read jokes, that's a BBS job. Oops, the Facebook generation doesn't know what that is. "Huh? What's that DOS thingy?"
