Having been part of a couple of subs take off, the key is to engage yourself. If a sub starts or you start it, add content that’s authentic and appropriate and then discuss things. Don’t force it but don’t let someone else do it either. It’s the only way. There were are a ton of dead subs at reddit too, usually because people stopped engaging for whatever reason.
The more users the more content there is though which is ultimately what I want as a user.
This is even more important for more niche communities a lot of which are still very quiet/dead/non-existent on Lemmy relative to reddit.
