You don't listen to Boortz?
If I'm in the car by myself, I will listen to talk radio. Otherwise, I don't. I can work to the tv and totally tune out to it, but I have never been able to have the radio, or stereo, on and do anything requiring concentration - especially anything involving numbers/math. When I had a private office at work, the overhead speaker was right outside my door, tuned to a local "easy rock" station, with no way to control the volume. I finally ended up getting a small tv, and keeping it on and the door closed, so I couldn't hear the speaker.
If Boortz would get a tv show, it would be great. I do like him.
