@scottjenson According to Joinmastodon.org, current Mastodon stats are 1m active users per month. https://joinmastodon.org/about
The peak of Mastodon activity was 2.5m when the Twitter/X rebrand happened: https://techcrunch.com/2023/07/24/as-twitter-destroys-its-brand-by-renaming-itself-x-mastodon-usage-numbers-are-again-soaring/
Even at peak, the engagement numbers have always been a drop in the bucket of the larger networks (X has something close to 550m monthly users) https://explodingtopics.com/blog/x-user-stats
I agree with folks in your comments, though - it's been serving my needs as a social network.
