Downing Street's microblogging team is monitoring us from the depths of the Prime Minister's bunker.

At least, that's what I deduce from the email I got this morning. In fairness, I'm 'following' Downing Street on Twitter, too. And it seems that they are automatically set up to return the compliment... well, while there's only a couple of thousand of us, anyway.
