An annual gathering of Internet and media enthusiasts since '94, ROFLcon is an epic Internet cultural conference. Go to catch a glimpse of your favorite Internet celebs, like Obama Girl, to commiserate with others about sucking at Photoshop (darn it if making LOLcats isn't harder than it looks). This year's event features a swathe of compelling talks, like The Cultural Impact of Comic Sans, given by the creator of the font, and Causing a Scene, by the generally pantsless founder of Improv Everywhere.
