Do you measure how tweetable an agency is by the number of staff who tweet? Or by your number of followers, or the numbers you follow? Or how often you tweet?
Surely it is about the quality of what you say on Twitter and how other people engage with your conversation.
Twitter is nearly three years old and the media have only recently picked up on it because of Stephen Fry, Jonathan Ross and the events of the Mumbai bombing.
When I first started using it in December 2006 it seemed a novelty, but its usefulness as a PR tool cannot now be in doubt – particularly with the advent of the Twitpitch.
