Bluesky

Bluesky is a microblogging network built on the open AT Protocol, which separates your identity and data from any single company. That design is the genuinely interesting part: you can keep your handle, follows, and posts if you move between providers or clients, choose from independent custom feeds instead of one company's algorithm, and even self-host your own server. It is worth being clear about the difference between the protocol and the platform, though. Open source does not mean free speech and the flagship bsky.app service run by Bluesky the company moderates heavily and has been widely criticized as censorship-friendly so the real openness lives in the technology and the third parties building on it rather than in the default instance. Bluesky also makes users prove their age where laws demand it, with a face scan or credit card in the UK, Australia, Mississippi, Ohio, South Dakota and Wyoming. It bars under-16s in Virginia and under-18s in Tennessee, and limits features for under-18s in Brazil and Texas. Choose it for portable identity and an interoperable social web, then pick or run a server whose moderation you actually trust.
