Bluesky has reached 40 million users, a rise from 38 million in August, but its growth rate has significantly declined. After an initial surge last year, the app now adds about 1.4 million users per month, well below its previous peak. Despite this slowdown, Bluesky remains relevant for its dedicated user base and has introduced new features to enhance engagement.

Threads has surpassed 400 million monthly users, showcasing its rapid growth and popularity as a social media platform. The increase in user engagement highlights the app's competitive stance in the social networking market.
