The protocol that the Bluesky app is built on, atproto[1], is designed to support other social modes. The Bluesky app is in some ways "just" a reference implementation of microblogging, created to ensure the protocol actually works for users and developers.
In early 2024, when the production network is federated, it will be possible to build new social apps on atproto that the millions of existing Bluesky users will be able to use (if they choose) without having to create a new account.
