Mark Wilson writes: For a man so readily associated with words — and certainly for a wordsmith so enamored with technology — Twitter seems like something of a natural home for Stephen Fry. Over the years he has amassed hundreds of thousands of followers, but last night he closed his account. Fry's latest exit from Twitter (there have been several over the last few years for numerous reasons) came about because of the backlash he received for making a joke at an award ceremony. Hosting the BATFAs (British Academy of Film and Television Arts) on Sunday, he referred to costume designer and award winner (and, indeed, friend) Jenny Beavan as being 'dressed as a bag lady'. 'Offended' Twitter users attacked Fry in their droves, and he fought a valiant battle, before eventually giving up and terminating his account. It comes just days after Twitter set up a new Trust & Safety Council.
