It was the interview everyone has been Tweeting about. Last night, Stephen Colbert sat down with Biz Stone, founder of the wildly popular social-networking and micro-blogging service Twitter. The discussion was interesting, hilarious and–perhaps most surprising–over 140 characters. You'll naturally want to go Tweet about this now. And when you do, make sure you're following @StephenAtHome, @CCInsider and @TheIndecider.The Colbert Report airs Monday through Thursday at 11:30pm / 10:30c.
