"Bluesky is a social app that is designed to not be controlled by a single company. We’re creating a version of social media where it's built by many people, and it still comes together as a cohesive, easy-to-use experience. We've done this by building Bluesky on the AT Protocol, an open source toolbox for building social apps that can all talk to each other."
