Most of the Talk Stations now are controlled by Clear Channel and are not programmed by XM.
Clear Channel has KILLED my favorite channel which was Extreme 152 and now programs it with political talk shows and RE RUNS of shows that aired earlier on other XM channels.
You can call in to O and A, or if your not happy with the programming you could send an email to eric logan and let him know. He does a pretty good job of answering most emails he gets.
