Bluesky, the decentralized social network, has reached 2 million users, doubling since September. Despite being invite-only, Bluesky plans to launch a public web interface by the end of the month and aims to implement federation by early next year, allowing users more freedom similar to Mastodon. Bluesky’s differentiation from Twitter/X emphasizes user choice and independence from private companies. While the AT Protocol is being developed, potential interoperability challenges with established protocols like ActivityPub may arise. Bluesky’s recent features include a public web interface and various enhancements, but its invite-only status has allowed competitors like Meta’s Instagram Threads to gain traction.
