Some of us have never quite got to grips with Twitter, but if you have, here’s a chance to write alongside some top authors:

Launching on 14 September 2011 for 5 consecutive weeks, Simon Brett, Neil Gaiman, Joanne Harris, Ian Rankin and Sarah Waters will lead a short story tweetathon in which authors and tweeters will collaborate to write a short story in 670 characters.

This is the brainchild of the Society of Authors, and it’s part of their campaign to mark (and if possible, reverse) the decline in broadcast time the BBC are giving to short stories. You can find out more here. Meanwhile I’m off to my very underused Twitter account, to see if I can work out how to spread the word.
