Brad Greenspan, the former CEO of Intermix Media, the company which launched MySpace, loves to make trouble for News Corp., the media giant he claims bought Intermix and MySpace for a song. Too bad he pays more attention to his ongoing, one-sided feud than his revenge vehicle, LiveUniverse. Greenspan's startup is having trouble with his uptime; a tipster says his LiveUniverse and LiveVideo sites have been down for two days running. That's not the real problem; the real problem is that it took two days for anyone to notice they've been down.
