Fred Seibert was one of the creators of MTV and Nickelodeon.  He's pioneered Oh Yeah! Cartoons and What-a-Cartoon.  Next New Networks is his current project, where he's trying to become the curator for online video.

I interviewed Fred a couple of years ago, when Next New was just launching.  He pointed out that there's a direct corelation between his personal success and the number of artists he knows.  To keep himself in the minds of animators everywhere, Fred runs Channel Frederator (a podcast of user-created cartoons) and Channel Frederator RAW, a digital watering hole for said animators.
