Great to see the BritBots event! (You know, where you use MSN Messenger or whatever to respond direct to user direction. You still don't? Not even the Encarta bot (encarta@botmetro.net). Well, give it a go: ask it a question)
Anyway, with all of the available APIs out there, I reckon we could see some great stuff. If nothing else, it'll make my contacts list look better.
Some suggestions from me...
OK, so you can do a lot better - but between those four, I'd probably never speak to another human.
