Great! Turns out this speech was in fact recorded successfully and completely by Justin.tv, but apparently some others like Arrington's were not due to technical difficulties (like I remembered last year.) I was actually very nervous because I made a decision to publish these notes to the public asap, but I was missing out on the first part of Paul Buchheit's speech to do so. Why was I nervous, when surely there would be perfect, uninterrupted video recordings , with full and clear audio after the event? Well...
