Christopher Poole is the publicity-shy founder of 4chan.org, which Time said averages 13 million page views a day, 5.6 million visitors a month, and could be the "second largest bulletin board in the world." Poole was 15 and living with his parents in Westchester County when he set up the site in 2003 to attract other fans of Japanese comics. He is Time Magazine's Most Influential Person of 2009.
