14=. Jimmy Carr, Comedian

Known for his bullet-pointed one-liners that occasionally nudge at the boundaries of taste, Carr has found Twitter an almost ideal home for his brand of comedy. The "almost" refers to a couple of occasions when he has fallen foul of the Twitter police in the traditional media, with unfortunately timed gags about car crashes (shortly after November's major accident on the M5) and air disasters (on the 10th anniversary of 9/11). Followers have been quick to forgive these lapses, but his output post-Christmas has been minimal. Perhaps he is saving up gags for his role as co-presenter of Channel 4's 10 O'Clock Show.
