Well, they acted like kids on the show, yes, but also note that Alex and Kevin worked together for years before that on The Screensavers. These guys were definitely kids together doing this stuff, and I can understand how they must feel like they've outgrown it.
I'm about the same age as these guys too, and I stopped watching about 2 years ago. I felt bad for them that they had to continue doing what they were doing even though they must have felt their age catching up with their antics.
Alex was on The Screensavers for like 3 months, after Tech TV was bought by Comcast and merged with G4. He was the replacement for Leo and Patrick, who were far more knowledgeable and competent.
