There used to be the Alexa ranking for websites but it seems to no exist anymore. Elsewhere I only could find for lemmy.world ranking (something like 55000, yay!) but not the actual userbase, and nothing about any other instance (let alone the entire Fediverse).
I think 50k MAU has been bandied about.
So pretty much stagnant as of now?
I remember this kind of sentiment in reddit back in the day before it went mainstream lol
No, just slow and steady
