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.

Yeah of course, it depends on the method and lot of things. Anyway, I agree with you, I’m happy with the content and the spirit of the users (less trolls and haters than on reddit or commercial social networks, more like the internet users I knew late 90s or beginning 2000s).
