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.

Pruning is a bad idea imo. Old communities here (like on reddit) can be great resources for solutions to technical problems, for example. And weird one-off communities that have like 2 memes from a decade ago can be really funny when you get linked to them.
Perhaps a notification-type nag, a tab of "communities you used to use but haven't posted to for a while" but with a snappier title, alongside "local" and "all".
and now PieFed supports moving posts! https://piefed.social/c/piefed_meta/p/1653370/piefed-1-5-is-released-move-posts-upload-video-files-better-chat-and-more
So Piefed admins/mods could consolidate communities by moving the posts before deleting the community
oh that's a great feature
Just to give you an example, I help mod a community called !askusa@discuss.online where we wanted to open up a space to discuss topics of interest to people in the USA, yet remain a safe space away from politics.
What then is there for us to talk about, these days, that does not involve politics?!?!? (this btw was the topic of my 2nd-to-last post, six months ago now)
I do not need a nagging reminder to help me realize what is happening here... :-(
