Call me a nerd, but I love an educational discussion that explores different topics. Stuff You Should Know is the podcast that got me into listening to podcasts almost exclusively. A factoid podcast that explores a different subject each episode, SYSK offers in depth discussion into topics varying from How the La Brea Tar Pits Work to How Avalanches Work. I try to keep up with their podcast, and I can honestly say that every subject is interesting, no matter how boring they may seem (Microlending anyone?). Each episode runs, on average, 30 minutes, but occasionally they may fall shorter or run longer. Hosts Josh Clark and Charles W. Bryant are both endearing speakers who manage to make every topic feel personal and enjoyable.
