Sources of Intelligent Audio for Commute?

confusus writes "Trapped in the daily routine of commuting for 1-2 hours every day, I started to ponder different ways of recycling commute-time waste. I tried listening to the radio, but 9.9/10, it ends up being just 'duh-whatever.' Then, I tried listening to audio books: it is really hard to find audio books that are tailored toward nerds. Thus I decided to find audio of interesting/geeky/nerdy/sciency interviews, talks, lectures. What would be the websites which provide such content?" I'd really like to find more informative downloadable audio content, too. Perhaps informed commentary and self-guided tours of historical and other sites, like national parks and significant buildings in the U.S. and elsewhere, basically self-guided audio walking (or driving) tours. Can anyone recommend a source?

Read a book!

Recycle car, then use a bus, and suddenly you can read newspapers, books, even program with a laptop while on the road. Most importantly, you don't need to care about all the idiots on the road. :)

I'd imagine it be cheaper too.

NPR

National Public Radio is awesome: Smart, diverse, interesting. They could use your financial help, too.

Guess I should turn in my nerd card.

On the other hand, I don't really give two hoots about audio in the go. I don't even own an old Discman, much less the trendier iPods and other portable media players, so...
