As I approached the TechStars Demo Day event in New York yesterday, the first thing I noticed was my blog title in lights. (Thanks, TechCrunch, for the photo.) The second thing I noticed is that no two "N's" were alike. The sloppy Webster Hall sign stood in sharp contrast to the incredibly well-polished pitches from the 11 startups inside. If the products and business models of those startups are even half as refined as their on-stage presentations, there will surely be some interesting winners from the batch.
