I would say that the decentralized nature of the platform means that the demographics that don’t get along don’t have to share the same space. Reddit is full of communities that fucking hate each other and the centralized nature of the site means that those userbases have to occupy a lot of the same subreddits; those users have a low barrier to entry to go troll each other and pick fights. In the Fediverse, these communities are separate instances and will just defederate from each other, putting an end to it. Instead, like-minded communities and instances can congregate together. The federation model also provides incentive for users to behave, since instances can be cut off from everyone else if they’re deemed too toxic/annoying.
Sounds like it’d improve interop. Make it so that there’s a curation system where communities can choose specific users/instances to watch for this content.
