I heard them use jokes I’ve only heard on Hexbear, but I kept chalking that up to “maybe this is just leftist twitter humor”. Now, I’m casually listening to the latest episodes and one of the hosts made a throwaway line about lathing something into existence. There is no way that bit is used anywhere other than Hexbear.
The only podcaster I know frequents the site is Yugopnik, and JT did an AMA like 3 years ago.
