Huh. Randall Munroe and Cory Doctorow met in person over a week ago, and the Internet didn't explode, or invert, or become the Virtù. So we need to come up with some new candidates for what event will trigger the Geekpocalypse. My vote is for when Randall and Summer Glau start dating.
They'd make a cute couple, wouldn't they? And she could use her mad ballerina skills to defend him from the pixel-eating bands of LOLzombies which will roam the Afternet.
