Decentralized social platform Bluesky, founded by Jack Dorsey, surges past 20 million users as ex-Twitter (X) fans seek refuge. To handle the user boom and combat rising harmful content, Bluesky is scaling its moderation team from 25 to 100. Meanwhile, Mark Zuckerberg watches closely as Bluesky challenges Meta’s Threads, which has floundered since Elon Musk revamped X. With no ads and a fresh $15M Series A, Bluesky champions user control and privacy.
