You gotta spread the word.
But, being real, it’s going to be slow. The nature of the beast with lemmy/kbin is that there’s a very long discovery process. So, not only do your have to spread awareness of your c/, you have to have those users be active on a lot of other ones, and feel motivated to share links on yours.
There’s the new communities c/ on lemmy.world (I think? Could be lemmy.ml, my brain is fried rn) though. It’s helped me discovery wise. And you can’t be afraid to do a little self hype. Like, when you find something to post on your magazine, tell/ask the person you’re borrowing from that you did so/want to. Provide a link to that bestof post as well.
Yeah, it’s shameless self promotion, but you won’t have to do it long, assuming the lemmy/kbin world stays steady.
Edit: make sure your link is formatted right for jerboa/app use as well.
I dunno, I was up and running in five minutes. You pick an instance, you sign up, you verify the email, and you’re good to go. What server doesn’t matter much, barring it closing unexpectedly and without warning. There’s not enough users to need more than a handful.
