I assume "heat death" most likely refers to the noisy ("high-entropy") backdrop of shitposts.

Community rules need to be enforced. Surely, like with every social group, there is a forming, norming, and storming phase.

Reddit has "norms" that make it look like people are communicating (image memes) when really they aren't. Image memes on reddit seem like an unholy marriage of autistic and neurotypical phenotypes that seem to have the disadvantages of both but no real understanding.

Somebody feels included by that but personally it drives me away.

Image memes.

I left proggit as soon as I discovered Hacker News because on proggit the people just can't accept that somebody somewhere might be motivated to program, at least partially, by the money. I went through a phase where Leon Trotsky was my hero but I still think of the people at proggit as "communists".
