Another fun part about SXSW was the Windows Mobile competition that I got to be a part of. I was invited along with Charlene Li, Hugh MacLeod, Tara Hunt, Steve Rosenbaum, Dave McClure, Chris Brogan, Erin Kotecki Vest (@queenofspain) and Deb Schultz to come up with a mobile application idea that the Windows Mobile team will actually build out. My idea? Critter: Twitter for pets. It's kind of lighthearted, but people do love their pets. Like it? You can view a video with further explanation and vote for it here.
