On the BBC Radio London breakfast show this morning to promote the book - which now has a second positive review on Amazon, thanks for asking - and got home to find that Twitter had signed me up to its new beta 'retweet' service.

I've got to be honest - I just don't get this one. It 'shapes' your retweets (when you repeat something someone else has said because you think it's worth saying) differently. People not on the new system just see the message with 'RT' in front of it.

I suppose there's a reason, but this looks a lot like one of those cases of someone fixing something that isn't actually broken.
