Ask HN: Good Podcasts?

I was wondering if anyone here could recommend any good podcast series. It doesn't have to be tech related. Broader science/history/culture would be great too -- but it should be informative.

A decent amount of my time is spent on the train or at the gym and I like to use it learning about new things. It's just that I unfortunately have not found too many great programs out there. I get the usual NPR stuff and enjoy Radiolab (although it's pretty infrequent) but am hoping some folks on HN will have some other suggestions.

Keith and the Girl, Red Bar Radio are just funny

Dan Benjamin, from 5by5 (http://5by5.tv) has several very interesting tech related podcasts.

I am addicted to the Stuff You Should Know podcast. Great choice if your interests are varied. They publish frequently and there's a huge back log of good topics.

My favorite one is "The Skeptics' Guide to the Universe". It has likable hosts and content that is entertaining, but often educational as well.

The level of commitment to the show by the Skeptic's Guide hosts is simply amazing. They have been producing great content every week since 2005. I would recommend starting at #108 and make sure you listen to #109 next to see just how committed they are.

I usually listen to the show while falling asleep or taking a bike ride.

"Planet Money", "Radiolab" and "The Moth Podcast" are good too.
