OCCUPATION: 4chan.org founder
PREVIOUS APPEARANCES ON THE TIME 100: 0
PRO: Just about every Internet in-joke of the past few years has started on 4chan a bare-bones, id-liberating and reliably profane image board whose Droogish users have hatched everything from Rickrolling to LOLcats. The site can also launch real-world movements, as evidenced by Anonymous, a 4chan-organized protest group responsible for several anti-Scientology rallies.
CON: Thanks to 4chan's oft-obscene content, the reclusive moot has had trouble luring advertisers.
