This weekend, team PopSci.com is temporarily relocating to warmer climes down south for the great digital mind-meld that is South by Southwest Interactive in Austin, Texas—the nerdier stepchild of the definitive SXSW music conference happening later this month. We're dusting off our conference caps to soak up anything and everything from keynote speakers including MAKE's Phillip Torrone, Dan Rather and the godfather of Spore, Will Wright, as well as sessions from just about anyone who's anyone in the Internet game. Chances are, if it's going to define the way we use technology and the Web in the next few years, it'll be talked about by someone in Austin this weekend. So obviously, we're pumped. Watch this special category page for our blog updates from the conference. —John Mahoney
