I guess I'm behind on this but I have just gotten into podcasts. Here's what I subscribe to:
General Interest: This American Life, Art of Manliness, Radiolab, The Moth
Humor: The Nerdist, Doug Loves Movies, AV Talk (the Onion), Hatecast (The Onion)
Music: Morning Becomes Eclectic (KCRW), All Songs Considered (NPR), Live Concerts from ASC (NPR)
Sports: The BS Report w/ Bill Simmons(ESPN)
Any other suggestions?
