Would you have put Rush Limbaugh on WWKB between Alan Colmes and Randi Rhodes? Why were there no local left leaning hosts on that station?
Because, as has been beaten to death here, WWKB isn't a "radio station" as we typically understand it. Since the moment the oldies stopped playing, it has functioned purely and exclusively as a blocker. As long as Entercom has it and is doing something minimal with it, nobody else can use it to compete against the big guns, WBEN and now WGR. The object is not to get ratings, and it's certainly not to spend any money doing anything local on the air or investing in any promotion. Any revenue that does show up, mainly from leasing time for Bisons games, is gravy. What makes WWKB "a success" is simply that it's not being used by someone else to draw listeners or revenue away from WBEN and WGR.
