One tip is that most of us “use” Lemmy a bit differently than Reddit. Most niche communities (with some exceptions ofc:-) here aren’t as active as they were on Reddit, so many of us end up spending more time in the generalized ones - e.g. !technology@lemmy.world rather than specific ones like r/OnePlus or even r/Android.
I know it’s now a cliché comparison but that was what early reddit was like. If you were a more recent redditors you need to realize it started smaller too, originally there weren’t even subreddits, and there was a /r/reddit.com once they were introduced.
That level of granularity largely won’t be necessary here for a while but I don’t mind at all.
Seconding this @Damage@fedd.it Lemmy has really shown me this first-hand multiple times. For example !connectasong@lemmy.world started out with a few regular posters but then there was couple mo th period where we all seemingly forgot. Once I remembered I went back and decided to just connect songs with my self each day until it came back. Turned out it worked in under a week.
But it can also take time. I made my own community was the only poster there for months, posting maybe average once per week. Subscribers trickled in slowly and then I found its subscirbers growing exponentially and now others contribute.
Remember, people are abandoning reddit slowly all the time, it’s not all grand exoduses, I see it as building a relatively active community for future users to find. !fedigrow@lemm.ee was recently created for more discussion in this area.
