Since I like to be thorough, I went digging, and sure enough the OC Register has the original story. In addition to warning BlizzCon attendees not to emulate any Blink 182 videos (a sound policy) it also has a pretty rocking picture of a woman named Carissa Creveling dressed up as a Diablo 3 Barbarian. Carissa, I'm sincerely impressed by your costume. Especially that axe.
So to sum up - don't be naked in public at BlizzCon, Carissa has a really cool Barbarian cosplay, and I'm going to be watching BlizzCon via the Virtual Ticket, so I'm going to be as naked as I want and y'all can just seethe knowing I'm free as a bird while you swelter. Teach you all for going to the party without me.
