After attracting 2 million users in its first year of operation, Bluesky has grown another 400 percent with some recent help from Brazil and Elon Musk. Are these monthly or daily users, or just account holders? Nobody knows! But it still has a way to go to match X’s estimated 250 million daily users and Threads’ 175 million monthly users.
True. So both have around 10 million total users. Bluesky has no monthly active user statistic. But around 1 million daily posters according to this https://bsky.jazco.dev/stats
While Mastodon has ~1 million monthly active users.
So sounds like bluesky’s got a lot more activity with that many daily posters, as of now, anyways.
