Twitter

Is anyone else using Twitter yet? I heard about it on the news the other day and thought I'd give it a go, but at the moment I don't see the point, as I can express myself here on the blog and am not limited by 140 characters per entry (and I can put in pictures which I know you all like). I invited some friends to join it though to see what would happen and so far one person has accepted. We shall see if I can be bothered to continue with it after more than a week.
