Podcasts

They aren't new, and I'm not the first person to say this, but it deserves repeating: Podcasts are awesome. I'm currently subscribed to ones from the New Yorker, the New York Times, Science, Nature, Scientific American, and for my required dose of Satire, HBO's Bill Maher and the Onion. They're all of exceptionally high quality, exactly as one would expect, and their big advantage over text (or video) is that you can let them run in the background and absorb their contents without having to look at your computer screen, while you focus on your work.
