An interesting development appeared last week called Tweetminister. MPs basically using Twitter to communicate.
I'm not sure how successful it will be but it could end being a source for diary and gossip columns if updates carry on in the same vein.
Tom Watson is on it for example, and what appears to be a response to a link to an online chocolate shop called Chocolate Buttons he said "I'm surprised one of my colleagues hasn't called for a ban ;-)". A joke, yes, but a hidden truth too perhaps!
Party political jabbing aside though, it will be inetresting to see how many MPs take it up, how seriously it is used, and also how many people start following them that are not party activists already.
