Noting the rankings, Bluesky CEO Jay Graber wrote, “good job Brazil, you made the right choice.”

That growth is particularly impressive for a platform that only fully opened to the public in February and winkingly acknowledged its small size (especially compared to rivals X and Threads) by describing itself as “the short king of social apps.” The company says it had more than 6 million users as of May 2024.

Bluesky was first announced in 2019 as a Twitter-backed initiative to build an open, decentralized social protocol. It has since become an independent public benefit corporation, with Twitter founder Jack Dorsey leaving the board earlier this year.
