Welcome to the board, TheEZ. Hope we hear from you plenty in years to come. Sometimes we get one-hit wonders who come in with an ax to grind about a particular talent or station, and then we never hear from them again.
That being said, this is an entertainment medium. Maybe I am old and jaded, but whether a bit is highly staged or just kind of staged, they are ALL staged to engage the listener. Not too worried as to which degree they are scripted out. Listeners are the product, and access to those listeners is sold for (hopefully) profit. The job of the talent is to keep as many of those listeners engaged as long as possible, right through the stop sets that they want the listener to engage with. Listeners don't know or care how the program is created, or how the music is created, or even where exactly the show is physically taking place. It's all theater of the mind.
As far as KISW being the only station left in the market that cares, that would come as huge news for the guys and gals getting up at 2 in the morning to go to work all over town, like at 97.3, 1000, 93.3, 710, 95.7, 94.9, 88.5, 1380, 1520, 90.3, 105.3, 92.5, 98.1, 98.9 and probably a bunch I am missing.
