Morgan Page In the air podcast
I agree with the "not listening to anything technical while commuting" comment. I always feel like I'm just going through the motions when I try to listen to something detailed while scrambling through airports and subways. It'd be different if I did the same commute every day (same highway, same subway, same bus, same pneumatic tube ala Futurama) and could get where I was going via muscle memory, but I'm normally in a different city every week and have to pay attention. I end up either listening to the podcast and missing my stop, or paying attention to where I'm going and not retaining any of the technical info. I just don't even pretend to try and opt for something that'll pass the time.
