Everyone's heard of Kevin Rose, the genial, constantly drinking founder of Digg and host of the Diggnation webcast. And everyone's used to his sleepy-eyed, mopheaded good looks. Well, forget the mophead. From this Valleywag spy photo pic we spotted on Yahoo executive Bradley Horowitz's Flickr stream, Rose got a buzz cut before flying to Hawaii for VC David Hornik's exclusive Lobby conference. Does this have something to do with that Captain America comic? How will his online-video fans react? Will his Diggnation numbers plummet? And will women continue to ask him to sign their breasts?
