17.Dara O'Briain, Comedian
In interviews, O'Briain has celebrated the dynamic nature of Twitter and its scope for sharing thoughts and ideas: "It's the open plan office experience on a massive scale... with 200,000 chairs or something." His own tweeted thoughts range from musings on science to reflections on the ineptitude of airline check-in desks. But it's his caustic side that resonates most. During last August's riots, O'Briain's frustrated and furious tweets (eg, "Hey parents! Does your 14-year-old suddenly have a plasma screen telly and 8 mobile phones? Where did they come from?") ricocheted around the network and brought thousands of new followers.
