I was on there when it was just Mastodon.social. It was more vibrant then, and it's been more vibrant in recent memory, before it rocketed to 2m users and started falling. Something is different, and it's not good. I think people who've been there are getting fed up with problems no one seems to care about years on (even people like me who kept giving it chances and pushing for change), and new people are going somewhere else instead of trying Mastodon.

You can stick your head in the sand if you want and hope the year-long freefall stops rather than consider there might be a problem. It's what I've come to expect.
