Verdict: Bluesky is a promising privacy-respecting alternative to mainstream social media. Its decentralized design is a genuine improvement, though the platform is still maturing and all posts are public by default.
Bluesky is a decentralized social media platform built on the AT Protocol, originally incubated within Twitter. It gives users more control over their data and feed algorithms through its open, federated design.
