The idea about voting isn't to select a "best" hack each night, its to say "take some time to find a better hack". That way if someone does get through the pre-screening you have a way to say, "take a couple weeks to think about your next Tell."

Granted the nation wide voting idea kinda gives the wrong impression on that part. I still think it'd be a good idea to keep videos somewhere.

Granted it was mostly just hand waving on how to keep the non-hacker attendees from overwhelming the hacker presenters.
