That's a good one, Josh, though it didn't make the cut after I started pod-catching The Best Show - one three-hour podcast is enough.
KCRW has a lot of good programming. I also like a lot of the other WFMU shows. There's always This American Life, and I listen to Democracy Now every day, though it's not exactly a rollicking good time. Leonard Lopate on WNYC can be a little insufferable, but he has good guests.
