I've resisted to urge to comment on the WJSE flip until now... it took me a while to form an opinion, and I just didn't feel like getting in between all the bickering.
But I will say that even as an alternative rock fan, I find it hard to get anywhere near as worked up about this as I did over G-Rock. And I have a feeling that a lot of people are in the same mindset as I am for similar reasons, thus the lack of protest. For me, in all fairness, part of it may be that I'm outside the coverage area... but I can connect this to the big picture by noting that G-Rock had much bigger coverage. Also, as Sean already noted, WJSE's playlist wasn't nearly as unique or adventurous as G-Rock's, and they played some bands that G-Rock rightfully avoided in its latter days. Finally, there is at least some solace in the fact that WJSE was replaced with somewhat of a unique format. It's not the full-on dance station that some people might have hoped for, but at least it's providing something other than a run-of-the-mill CHR or AC format.
