Bluesky har vuxit kraftigt – kört om Threads sedan valet

Bluesky is a decentralized microblogging social networking service modeled after and inspired by Twitter. Users can share text messages, images, and videos in short posts. The service is primarily operated by Bluesky Social, an American benefit corporation. Bluesky is chiefly a reference implementation of the AT Protocol, an open communication protocol for distributed social networks. Bluesky Social promotes a composable user experience and algorithmic choice as core features of Bluesky. The platform offers a "marketplace of algorithms" where users can choose or create algorithmic feeds, user-managed moderation and labelling services, and user-made "starter packs" that allow users to quickly follow a large number of related accounts within a community or subculture. The AT Protocol offers a domain name-based handle system within Bluesky, allowing users to self-verify an account's legitimacy and identity by proving ownership of a domain name. Bluesky began in 2019 as a research initiative at Twitter, becoming an independent company in 2021. Development for the social app accelerated in 2022 after Elon Musk's acquisition of Twitter and subsequent severing of ties between the companies. Bluesky launched as an invite-only service in February 2023 and opened registrations in February 2024. Jack Dorsey left Bluesky Social's board by May 2024.
