I have just signed up to a Twitter account. Many people (including some commenters) had urged me in this direction. But, in the end, the reason I took the plunge was very simple. Fiona Maddocks had given me a bit of much needed support on Twitter in the face of AA Gill and his "how could someone from Newnham understand a willy?" line. (Let him come to Newnham, I say...There's an invitation, Mr Gill!). I couldn't find her email address to say thanks, so I signed up to Twitter to do it that way.
Soon enough I found had some good friends "following" me.
So what now?
