Today's candidate is Mr. Marc Maron's WTF podcast.
I was first exposed to Marc Maron via the old Air America radio network. He was funny, sharp, and a generally insane liberal flamethrower. Which I like. Later, I was a very early adopter on the WTF podcast. I have no idea how I found it, but I would guess I found it within the first half-dozen episodes. His background as a standup means that he knows lots of interesting and funny people and is able to have some really interesting conversations with them.
Anyway. Maron is cool and funny, and it's a good show, but I find myself deleting 90% of the episodes without listening. I will probably check in again from time to time to see his guest list, but I'm giving it up for a while.
