I met my other half in a computer game :D He was a scantily clad half-elf with big boobies on display.
Twitter sounds interesting. I could be tempted to sign up and tweet.
I joined Myspace a while back because everyone said it was fantastic. I just don't 'get' it. Yeah, right, a blurb about me and a friend or two, haven't touched it for yeaaaaars now. Can't see FB being any different, except the MIL thing.
I have yet to be tempted to join facebook. I hear the MIL has a page there, as do one or two other people I know around the place.
The ones I talk to online all say they hate facebook and it annoys the crap out of them but it is a necessary evil and they can't get rid of it.
