I just finished spending the last two days at the Personal Democracy Forum's annual conference in New York, "Rebooting the System." In addition to learning from technocrats and politicos buzzing with great ideas and insights, I had the opportunity to moderate a panel entitled, "Mastering the World of Online Video." It featured three YouTube greats - Robert Greenwald of bravenewfilms, Josh Marshall of TPMtv, and Matthew Sheffield of NewsBusted. Each had some great thoughts to relay on how to succeed in the world of online video.
