Dan Abramov says asking for Bluesky's instances is a category error (overreacted.io)
His argument is architectural. Mastodon bundles hosting and app into one server, so federation is server-to-server and identity is tied to your home instance. ATProto splits them: your data lives in a Personal Data Server, while apps aggregate across everything, like Feedly over the whole blogosphere.
Engineers in the thread pushed back hard. There's one PLC directory, a handful of relays, and in practice one AppView, all mirroring Bluesky's moderation. Decentralized in protocol, one company in practice.
