As I was saying to my buddy today .. if I were someone that just signed up for Stern, I would definitely cancel. The amount of time they take off is ridiculous. They work four day weeks and then take off for 10 weeks (according to them .. it feels like more though). I, however, am addicted to some of the other stations on Sirius like Alt Nation. Its on almost exclusively when I'm in my car and its still a hell of a lot better than testicle radio with their incessant commercials and playing the same 10 songs over and over.
EDIT: I gotta say though, when they're off, I enjoy the format they're doing today the most .. the mammary lane stuff. Its short and to the point and you hear the good stuff. Whereas master tape theater tends to be boring.
