Chris Clarke, who runs the Creek Running North environmental blog, has developed an Internet argument bot called BlogWarBot. When I first read this I thought that it might trawl the Net looking for blogs to start an argument on, but in fact it's fairly tame and will only hurl abuse at you if you visit its site and start a conversation with it. As you can see from the following interaction I had with it, it's not particularly advanced, but anything to waste a bit of time on a Friday afternoon, eh?
