It's easy to rip on G4 right now. Almost two years after the network bought out the (somewhat) beloved TechTV and they slowly but surely eliminated every trace of the tech oriented network. They canceled The Screensavers, losing industry icons Patrick Norton and Leo Laporte and replaced them with Kevin Rose and Sarah Lane. They didn't last long as the show was re-branded and Kevin and Sarah both left. Kevin Rose went on to found Digg and become a paper millionaire and Sarah Lane married a co-worker and is now wondering the Earth.
The folks at G4 weren't done. They then killed off other quality tech shows like Call for Help and replaced them with crappy Fox castoffs and "The Man Show". They did make a few good move by buying the rights to Star Trek and Star Trek:The Next Generation but then crapped all over it with the "2.0" experience. The 2.0 refers to adding message tickers, stock symbols, and small factoids to the screen which making watching the show a nightmare.
