The one I listen the most and for the longest is No such thing as a fish.
Other that that, Better Offline, Darknet diaries, Money Stuff, Search engine, a local politics one that I disagree with but I use to be aware of what my local conservative pseudo fascists are arguing about.
And not so regularly many others whenever there’s an interesting episode.
Currently Dan Carlin’s Hardcore History. Love it because he’s good at the storytelling and there aren’t a lot of sponsored segments like other popular shows.
The Rest is History - two historians, Tom Holland and Dominic Sandbrook go deep on interesting topics from history.
Never Post - a podcast described as “about and for the internet” and in some sense the spiritual successor to Hello Internet but also reminding me of classic Radiolab. Worth checking out.
Another Darknet Diaries fan here. Very approachable, centered around cyber security and privacy. It’s the only one I am currently listening to, but I am going to check out some of the others from this thread.
