Here's my current podcast list.
Freakonomics Radio
By Steve Dubner, one of the authors of the popular Freakonomics books. If you like those books, you'll like this podcast.
Art of Manliness
AOM is a long-running blog, ostensibly about being a better man. In reality, these articles, and now podcasts, apply equally well to all homo sapiens, not just males. Recent topics have included: The renegade WW2 pilots who helped win the war in the pacific, The importance of building your social capital, How Jesuit spirituality can improve your life.
Smashing Security
A podcast about computer security, but the hosts discuss all kinds of related (and nearly related) issues. The show is usually pretty funny, and I frequently look up things I first heard about on this podcast.
intelligence squared debates
A formal debate format. Each week there is a topic, and two teams take opposite sides. Opening arguments, rebuttals, and Q&A from the audience. Then the audience votes, and one side wins. Recent topics have included: Do we need God less the more we evolve?, Does humanitarian intervention do more harm than good?, Have dating apps killed romance?
WorkLife with Adam Grant
A podcast about organizational management, by a recent popular author. Honestly, I don't think this podcast is very interesting. I think it's all pretty basic stuff that has been well-covered elsewhere. I'll give it a couple more episodes and remove it if it doesn't get better.
Car Talk
Do yourself a favor and get this one. I listen in the car on my commute, and I'm laughing so hard I can't see the road through my tears.
The Planner and the Geek
Vanguard's new podcast about personal finance issues. They have only produced two episodes so far, and I would say the hosts are still getting accustomed to the medium. I have great hopes for this one, though. I'm hoping it gives us a lot of inside information on Vanguard, it's funds, little-known tips and tricks, etc.
Mad Fientist
Needs no introduction. Brandon has one of the top blogs in the personal finance sphere, and he interviews plenty of other top thinkers in the industry.
