Long before he and Flickr cofounder Caterina Fake spawned daughter Sonnet, Stewart Butterfield had a manly thatch of russet facial hair that screamed "Daddy." He's thus the natural winner of Fortune's first beard-off; other contenders like Steve Jobs, Larry Ellison, and Yelp's Russel Simmons might as well not have bothered. There's one curiosity about his win, though: Why would a judge praise Butterfield's beard for being "trimmed nicely, edgy, yet mature, so he doesn't look 18 sitting in front of investors"? We don't think judge John Allan, the owner of a chain of grooming clubs, has any special insight into Butterfield's career plans. But he's nonetheless on target: We've heard Butterfield, who sold Flickr to Yahoo more than three years ago, has left Flickr general manager Kakul Srivastava — his "hero" — in charge of his startup baby, so he can tend to his real one, and is ready to bolt from Yahoo.
