I've been one of the people saying "we don't need more users. we need quality over quantity" and i was wrong.
the way it's going, lemmy needs active users who post content sothat the network stays relevant. networks like the fediverse benefit from network effects and that means that if we have more users, that improves the value and quality of the fediverse overall.
So please, everyone, when you can, make advertisement for the fediverse in your personal area. Go talk to friends, make attractive stickers and put them everywhere, stuff like that. We would all benefit from it.

Lemmy is great in the techy/gaming, memes, and news/politics fields, but doesn't have strong secondary communities. I no longer have a reddit account but still lurk to keep up with news focused in Ukraine, Japan, Korea, music, history, minecraft, etc.
Also, social media uses the same tactics as casinos to keep people hooked. I remember a podcast in which they compared the new algorithms to slot machines where sometimes you "win" by getting content you're looking for, sometimes you lose by getting fed random crap you didn't search, and mostly you break even & get fed the same repetitive crap (this makes the times you "win" seam more rewarding.) Social media is an addiction and cancerous to modern society.
