Boorus ought to be halfway there. They’re content-centric and high-bandwidth, they tend to have a theme, and they live or die by worthwhile tagging. But they’re not a feed, the way most federated platforms have been. They are not social media in any sense. They’re image hosts, minus any the incentive to create attention-sucking antipatterns.
Maybe with a more unified user experience - and ideally some P2P elements to make hosting cheaper and sturdier - we could fucking finally have a place that just hosts drawings. We’re a quarter of the way into the twenty-first century and it is absurd that every gallery site has some arbitrary limits on what content is too weird.
Tumblr used to be the exception, until Apple destroyed them. Bastards.
