It's one thing for knowledgeable persons on the outside of a [radio station, in this case] to speak on a sensitive topic, serious revenue decline, (however accurately). It's another thing for a [station] insider known to the public as such to speak up similarly about the same topic - thereby proving it. This adds a public perception problem. I think he'll catch a finger wag for this one!
Then again, if people tune in to listen to this guy, and he says his audience is declining, what does that say about his ability to attract an audience? Isn't that his job? The station didn't hire him to be their lawyer. They hired him to be an entertainer and get people to listen so they can sell advertising. If he's saying his audience is declining, the finger really points back to him, doesn't it?
It's like the sports team firing the manager when the team plays like crap. The manager isn't the one on the field. It's the players. They get paid top dollar to entertain. When the audience goes away, shouldn't the on-air people take some responsibility?
