The number of registered users of the "decentralized Twitter" project Bluesky has exceeded 20 million.
As previously reported, Bluesky (AT Protocol), a decentralized social project funded by Twitter founder Jack Dorsey, released its Android app on April 12. Currently, there are only 25,000 test users. New users need to join the waiting list or get an invitation code from their friends to use the app. (Forbes)
