@Mike Brock - Just listened to The Progressive Bitcoiner episode you were on. Your discussion of meme culture made me think of this other podcast episode you might find interesting: 
TLDL: The podcast presents Ruby Justice Thelot’s case study on how communicative “third spaces” can exist on internet platforms (in this case, tens of thousands of YouTube comments accumulating over almost a decade under a video for the soundtrack to Donkey Kong Country 2: Diddy’s Kong Quest)—and some of the challenges censorship or centralized platforms may pose to those structures. It dovetails into a discussion of what that means for the “Balkanization & Babelification of the Internet,” which is just a more academic way of saying “how online echo chambers are created.”
I find it to be a pretty compelling anecdote for thinking through the value of things like censorship-resistance, accessibility, and the role of media and platforms generally.

Remembering Checkpoints, an obscure YouTube phenomenon that can teach us a lot about the importance, and fragility, of online community spaces.
