1.)What do you think of talk radio? Is it too simplistic on the issues that we face today?I assume we're discussing only politcal talk radio here, since much of talk radio is about legal, financial and medical advice, gardening, home improvement, child care, computers, sex, people's personal problems, and a good many other things, most of which don't interest me.
I like political talk radio very much, and that's what I mostly listen to when driving, depending of course on what shows are on. The problem I have with it is the nature of it as a broadcast medium. That necessarily means a limited number of stations and shows, and so I often can't hear the ones I want, like for example, Larry Elder and Neal Boortz, a couple of my favorites.
Sure, they're a bit superficial, since time is limited and they have to keep the pace up to keep listeners. That's an inherent limitation of both TV and radio, and there's nothing to be done about it except to get your news analysis from newspapers, books, magazines and the internet instead. All of those have limitations of their own of course.
2.)Do we need legislation to regulate the balance between right and left on the airwaves that the public owns?Why yes, we sure do! NPR gets taxpayer money, yet tilts pretty sharply to the left. That should never be allowed!

(J/K -- Though NPR is strongly biased to the left, that's not really a problem. There's plenty of other PoV's present elsewhere.)
But in the private sector, it should be strictly hands off. What kind of left/right balance ensues is none of the gummint's danged bizness, and the market is taking care of it just fine, thank you. That the airwaves are publicly owned will soon be a technological anachronism anyway, as satellite and internet streaming become the norm.
3.)Do you prefer talk radio or national evening news?(i.e.-ABC,CBS, NBC)They're not in competition. Talk radio offers news analysis from varying PoV's with conservative being the most popular. The networks offer news with a leftish bias built in. Cable TV offers both news and analysis, with some choice of bias. Oh, and I forgot C-SPAN: they really are unbiased, about the only place you can find it, but that's because they say nothing and jsut roll the cameras.
I tend to rely largely on the internet for both news and analysis, and just use those other sources to supplement it.
