Number of (active) Lemmy users seems to stabilize and I think this is a great thing. Indeed we got a lot of users when reddit shutdown its API (I was among them despite being a long time oss user), many have left, but the community seems now to stabilize to ~ ½ of the big grow in june '23. I think this is very nice for lemmy, we can be proud of this project.
The stats come from: https://fedidb.org/software/lemmy
Eh it's only just stabilized, now is exactly when we'd expect efforts for natural growth to become active. Worth noting, at this point growth probably comes from Mastodon not Reddit.
