What sort of thing are you after? News, politics, true-crime, drama, comedy, satire, history, language, cycling, footy, other sport (apparently there are more), science (can't help with that), documentaries?
There's a massive range of comedians interviewing other comedians, and lots of instances of comedian B interviewing comedian A on Comedian B's podcast after Comedian A has interviewed Comedian B on Comedian A's. Some good, some bad.
The second series of 'Conflicted' is running at the moment:
The award-nominated podcast, hosted by Thomas Small, a Middle East expert, and Aimen Dean, a former jihadist turned British double agent inside Al Qaeda, is back for a second series. After exploring the War on Terror in series one, they’ll be turning their attention to the New World Order in new episodes
Fascinating stuff.
It finished a long time ago but the Onion did a piss-take of the Serial podcast called
'A Very Fatal Murder' which I found very funny. I don't think listening to Serial first is a pre-requisite.
And on the subject of Serial, the same people did one called
S-Town - murder and seediness in small-town Alabama (though the S in the title is an abbreviation of 'shit' rather than 'small') featuring a larger-than-life horologist.
American politics. I'm sticking with The Rachel Maddow Show (cos I'm a bleeding heart pinko liberal), despite the creeping in of ads and trailers. I was getting a little jaded by the primaries but, hurrah!, coronavirus has come along and she's now shedding a bright light on American government incompetence (also helps take the mind away from UK government incompetence).
Comedy - Athletico Mince. With Bob Mortimer. Say no more.
The Bellingcat people have a podcast. Just one series so far, on the downing of the Malaysia Airlines plane over Ukraine. You'd think they'd be better with a visual medium but it didn't stop this being a good solid piece of investigation. Apparently the Russians did it.
Gossipmongers - simple premise. 3 people, including Joe Wilkinson, read out gossipy stories and rumours from contributors and vote on the best. I do laugh out loud sometimes, but not as much as the presenters, who have a whale of a time.
