There is some excellent radio to be found, but you usually have to either look online or do a wee bit of research about the stations. College/Uni radio stations are often pretty good for music as they usually have quite a broad range of specialists, admittedly there is some crap on there (as most people on these stations have less than 3 years experience) but that can be part of the fun as it can be a lot less orthodox.
I'm still on student radio myself so I find it interesting to read peoples opinions. If I'm honest I stopped listening to radio for many years because I got sick of adverts, cheesy/vapid presenters and a lazy playlist. But there really is much more out there.
The highlight of the radio WORLD occurred the other night. I was doing a 36 hour radio show for Comic Relief and had a Skype interview with Shanks and Lund of Doomsday Arcade 'fame.' I'll podcast it another time.
So yeah, please know that there IS good radio out there. The more people who listen to it, the more likely that other people will take note. By completely ignoring it as an entertainment medium, the smaller stations will struggle and the big ones that are (mostly) crap will carry on. Examples of people with good radio shows?

I also tried to get an interview with Yahtzee. He never replied. I haven't hit the dizzying heights yet.
