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
Oh well, just wait till inevitably reddit does something stupid again and those numbers will go sky high again.
Also, if twitter where to fail eventually and a lot of people join mastadon, I think the amount of people using lemmy would also go up because people get familair with the fediverse.
