Sorry to be missing Day 3 of TechCrunch Disrupt. First two days were completely refreshing. Bizarre, but refreshing. Great to get out of the office bubble and be reminded just how many good, smart people there are in start-up land. (Not that there aren't also a lot of duds.) Companies I'd suggest keeping an eye on, in no particular order: TwitBitz, Quixey, Cake Health, Smolk Signal, and Bitcasa.
