Congrats to the folks at SocialMatchbox for putting on a great DC startup competition.
My favorite presentation was by Ben Slavin of HelioGraph. A truly simple, "why didn't I think of that" business concept that he's already gotten a lot of traction with. I love Ben's mantra along the lines of "80% of the functionality for 10% of the cost," referring to companies like Akamai that have completely missed the small to medium sized business market for website optimization.
Here is the event, presented in two videos, parts 1 and 2. The videos are long, so they might take up to 30 seconds to start playing.
