I'm all a-Twitter

I've been twittering (see my page at http://twitter.com/paulrpotts). I'm not sure if I'll keep up at this rate but it is convenient to be able to write little posts from my iPod. Twitter seems like an interesting social experiment. Like all these tools, a bit of a solution in search of a problem. Does it actually enhance a person's sense of social contact or just make us more isolated? So far for me I've been chatting, albeit in 140-character chunks, with a couple of my friends I don't talk to very often. But time will tell.
