The 250 shows supercharged viral growth, more than tripling to 806 in four monthsBack in March, very special correspondent Paul Boutin revealed that the Olds were derisively referring to the insular San Francisco clique of Web hipsters — the sort of people who Twitter about how they wish FriendFeed had a better Plurk API — as "the 250." After learning that 806 people tuned in to watch Kevin Rose shave his head, live on the Internet, we are now revising that figure upwards by a factor of 3.224. With Rose's market-expanding efforts, we now have three times as many people to mock. Thanks, Kevin!
