You'll see from the box to the right that I'm now putting the twit into twitter. I've never been a big fan of facespace or mybook, but twitter is, currently, urm fun.
Ignore the marketing twits, the pr twits and there do seem to be a number of interesting twits written by real people (famous or otherwise). Of course the term is tweets, but you know what I mean.
And of course twitter doesn't tell me that I have no friends. I know that already. www.twitter.com/coljones
