Maybe I'll hook it up to an accurate user count bot at some point, but anyway: There are 2,728 Mastodon servers online today and on them, there are 252,893 monthly active users, a number that increased by 45,517 since Jan 11th.
@Gargron Interesting. The servers number is identical to what the-federation.info shows ATM. I expected the real number of online servers would be a bit higher (because adding newest Masto servers to the stats hub is an irregular process).
Server run by the main developers of the project
