Kate, I appreciate your earnestness and passion. There's a severe shortage of both in the world today.
Unfortunately, petitions and protests aren't the way to change these things in radioland or even broadcastland for that matter. As Media Hack Chris ably pointed out, ratings and revenue are how things work in commercial radio. Period. If you have a good product aimed at the right people, you can do well. I wrote somewhere else KLSD was never marketed or sold properly, and while I may be wrong, fixing those ills would've at least given the station a longer lifespan than signing a petition as if you're trying to get the original Star Trek renewed for another season. It just doesn't work like that in this business. As sympathetic as I am to where you're coming from, it's not a conspiracy, it's just business.
As a result, you're unlikely to find much love or interest at this board, just some condescending sniping. San Diego IS a ripe market for progressive talk, and KLSD seemed to have the goods, but in between the programming it was clear there was some empty space. You just have to have an aggressive sales plan which tries to sell the station as something more than a multi-station buy, and doesn't behave as though the station is only catering to O.B., South Park, or exclusively to hippies (are there even hippies around anymore?).
