Working at WHQR (my top station, if there be doubts) as the webmaster, I think a lot about radio, and what makes good radio. There are some generally agreed upon production standards that can help programs sound good or bad. There are basic problems, like that one dj who always plays with the zipper of his jacket on-air so you can't think about the weather advisory he's reading. All you hear is zzzzzzip zzzzzip zzzzzip. Beyond basic sound issues like that, though, it starts to get wishy-washy, creative, and cool.
