Fediverse

Something along these lines seems more realistic to me. There will always be a place for easy, safe walled garden experiences with a low barrier to entry. In the fediverse, that could be a very large, curated instance where a broad group could find what they want without having to figure out how to subscribe to federated communities. Similar to how so many people were introduced to the internet via Prodigy, Compuserve, AOL, etc.
