The rote nonanswers Craigslist founder Craig Newmark gives in interviews are normally snooze-provoking. But Stephen Colbert makes them hilarious. When Newmark humbly claims he sees no reason to make more money with his comfortable lifestyle, Colbert replies, "to rub it in someone's face." Colbert also plugs Newmark's latest attempt to change the world, the DonorsChoose charity, because of a program which submits donations in the name of presidential candidates. Who's leading? That's right, Stephen Colbert, master of the plug.
