Kinda depends on what you're looking for. Going through my podcast app:

Dimension 20 is a bunch of CollegeHumor actors doing DND campaigns. I don't play DND but have enjoyed this so far.

The Dollop is a couple comedians riffing about strange people and events from history. More entertaining than educational but you might expand your knowledge a bit as long as you don't put too much weight in their research.

Blowback is a history podcast that goes over major historical events that people probably know of but not much about. The production quality is amazing and the research is really good. It's like listening to a well-made documentary. Plus they got Jon Benjamin as a guest actor for season 1.

Welcome to Nightvale is a surrealist horror/comedy with a fun vibe. Lots of memorable one-liners.

My Dad Wrote a Porno is pretty funny, although I felt like the bit sort of wore out after a few episodes and stopped listening. Seems to have an audience and still be going so maybe it picks up.

Citations needed is a solid critique of news narratives.

Monday Morning podcast is okay if you want to hear Bill burr rant to himself for a while. He's been doing it for like 13 years so there's probably gold in there, but I think he's better when he has someone to riff with. Only listened to a handful of episodes though.
