Any tips?

1. Be ok with the fact that there is less content and less stuff going on. That’s a fact. Simply because there is a lot less of us actively participating.
2. Start participating a little more yourself (if you don’t already, obviously). Because it’s the only way 1. will change: more participants means more content available, means more attractiveness to potential new users that will then also feel more motivated to participate and create more content ;)
3. Filter it the shit out of Lemmy.
   I don’t care about the vast majority of ‘political’ content or memes (sorry guys, nothing personal, I’m just too old (and too ill) to waste the time I have left with that). So, I quickly learned to filter those out and almost never see any (which means even less content, btw). My home feed is ‘Subscribed only’ and I’m also not afraid to block someone the moment I realize they’re only there looking to create trouble (here again, they’re not worth my time and attention).
4. Like suggested already, subscribe to !newcommunities@lemmy.world, !fedigrow@lemmy.zip, & !communitypromo@lemmy.ca to see what’s going on. Fedigrow is a neat place to see where people are actively trying to promote and grow their community (something I used to do myself but had to give up a few months ago, hopefully temporarily)
