I don’t care about “number go up”.
Lemmy now has enough users to provide plenty of content, and really interesting new communities I’ve never seen on that other website are starting to pop up.
It also has its own memes and culture already.
You don’t have 1000 comments under every meme post, but the comments that are there are usually worth reading.
It’s not a reddit replacement - it’s much better.
Maybe not every niche needs a dedicated community.
