Just make sure to adjust your schedule so you're on the road at the appropriate half hour time slots for your tastes and I'd say "bug closed"!
NPR listener demographics disagree. http://mediad.publicbroadcasting.net/p/wnmu/files/MasterMedi...
What I get from the bar graph is that not listeners skew male, educated, old, affluent, etc relative to the population. But I'm not sure how this even relates to the original question of whether there's something for everyone... even if there were no skew, what matters is what percent of the population listens. If it's less than 100%, there must not be something for everyone. Or if you look at it from another perspective, no demo is completely missing from the listener base therefore there's something for every demographic.
What a cool program if you think about it. I wish more highschool was tangible skills like that.
