Umm, well actually, Stern's going to Sirius, not XM. And that makes me very, very happy. I've got XM.
Stern used to be funny once in a blue moon, but too much of a jerk the rest of the time. He's not the first shock jock -- there were others years before him. He's getting his butt kicked in many markets -- especially if you look at the market segments that advertisers go for. And, no, the FCC (for better or worse) isn't going after only him -- Janet Jackson/CBS, Opie & Anthony, and others have had worse problems. But he'd have you believe all of those things were part of a plot to get him.
I don't care if anyone else listens to him, it's just that I find him boring and not very funny.
