How is the size of Lemmy's userbase changing? Is it growing or shrinking? How diverse is it? What do the current trendlines look like as we approach a year since Rexxit?

I feel like I used to see graphs on this sub fairly regularly, but haven't seen one recently. There was also some ambiguity in the numbers as commenting and voting were added to the active user totals. Now that most (all?) instances have switched to 0.19, do we have a better idea of where things stand?

Aside from sticking around and posting, commenting, and voting, is there anything users should be doing to help grow the platform? (!lemmygrow would be a good name for a sublemmy, if anyone wanted to organize something)

In any case, thanks to everyone who has helped grow Lemmy to its current size!
