Lance Twitters, Do I?

Just when I think I'm catching up with the techno wave (I finally got a cell phone!) I find some new cool but totally unnecessary gadget. I'm fascinated with Twitter. I know it's only new to me, but I've been following the Tour of California via Lance Armstrong's Twitter feed. This guy continues to amaze me. He's either the most amazing, accessible, and savvy athlete ever, or one heck of a con artist. I don't want to hear anything about blood doping.
