Multimap have been integrated their service with Twitter to produce….their Twitterbot.
What is it you ask? Well, to be honest, it is a little arcane, and quite a long way from being natural language. It’s definitely cool, because Colm says so - but guys, surely you could a better job of explaining what you might actually do with it 
?
Where I think this could get very powerful is if someone builds a mobile app that fires off SMS to Twitter with GPS data – and allows the user to build up a library of regularly used commands. Or would that cannibalise the current Multimap mobile offering?
