CAGcast is not the worst podcast, I've heard some pretty amerteur ones that make the CAGcast seem like professional radio, but it doesn't belong in the same list as 8-4, player one, joystiq, bombcast etc. Wombat and Shipwreck are pretty good but CheapyD's arrogance and voice can be hard to listen to. Also it seems like almost on a weekly basis they spread misinformation or aren't fully educated on topics they are discussing.Worst: Cagcast
Best: 1up Podcast. I listen to it every week.
