Like, I see all these other shows making podcast empires (Chapo has one, Rev left has one, etc.) while the podcast of the website continues to only be featured in Intercepted once. You'd think there would be more crossover between them and other left shows considering how popular Gramscian critiques are.
A bunch of these guys circulate through the Atlantic Coast comedy circuit. That's the straight line from the Street Fight/Chapo to WTYP/Trash Future subsects, anyway.
The Street Fight Radio guys Brett Payne and Bryan Quinby got Will Menaker into it. Then he roped in a few weirdo comedian internet friends and they roped in their friends and now you've got this long loose network of '00s-era college leftists doing mass media. Something similar must have happened in the UK, because Riley's at his own nexus of history and news on that side of the pond.
COVID really drove up both the listener and creator sides of podcasting. But there's definitely a cascade effect.
