The platform crossed the milestone last night, and it happened about a month and a half after the 25 million mark. Bluesky still has a long way to go to pass Threads, though; Meta’s platform has more than 100 million daily active users.

About a million active users each month
Edit: Damn, 10 million users, 1 million active daily, see other comment. My source was this, the one from the other comment is certainly more trustworthy https://adamconnell.me/social-media-platforms/#%3A~%3Atext=larger+social+network.-%2CStats%3A%2Cat+the+end+of+2022
which is less than bsky, but more than lemmy.
I think a lot of people get sucked into the idea that more is better. But that isn’t necessarily the case. I don’t think any of us really want to talk to a million different people anyway. We just want to talk to a suitable subset.
