I’m not a huge podcast listener but I do listen to a few of them.
In the past few days I listened to a bunch of episodes of Stuff You Should Know and are great (listen to the one about decapitation, absolutely worth it) and I just finished episode 003 of On Margins, Craig Mod’s podcast, and is a very interesting episode.
I’ve been a fan of Craig’s work for quite some time and his podcast is very well made and covers a topic that’s fascinating. Plus he's a very well spoken guy which helps when you host a podcast.
So there you have it, my two recommendations, Stuff You Should Know and On Margins.
