Besides Serial.
  1. The Great Debates.
    Extremely intelligent comedic debates. And short. Like nothing else. http://bit.ly/1wXcv0n
  2. Scriptnotes.
    The gold standard for screenwriting podcasts. Fun to listen to even if you're not looking for help. http://bit.ly/1wseRR0
  3. The Dinner Party Download.
    Kind of too good to be true in terms of how many interesting things they put in each episode. http://bit.ly/1wseRR0
  4. Studio 360 with Kurt Andersen
    Very smart and endearing interviews and other stuff. Choose an interview subject you like.
  5. Here's the Thing with Alec Baldwin
    When it's a great guest it's incredible. The one with Jerry Seinfeld is one of the best podcast interviews I've ever heard. Thanks to @ricky for introducing me.
  6. Zero to Travel
