Hey welcome! Sorry for the people acting like they know everything and being a bit rude about it.

So they are right, they don’t exist, but I can tell you that there is a demand! Trust me I run some niche communities and there are people here.

The catch is that you will need to lower your expectations. Lemmy for sure follows the 90-9-1 rule. For any community you’ll have 90% lurkers, 9% will comment, and only 1% will post. This means a couple of things.

First, that you have to be the change you want to see. If you want a community that’s awesome! Lemmy will allow you to grow it! However, for quite a while you may be the only one posting, and it feels awkward. It will pay off eventually though.

Second, to help mitigate that, I would combine your separate communities into one. We dont have the numbers to justify 3 niche ones. 3 niche will be lost forever, but one general could be successful. Then if people think it’s time to shard one off to its own community, that’s the time to do it. Until then, use tags to help separate the posts.

I wish you luck on your journey! !communitypromo@lemmy.ca is a good place to start, along with !fedigrow@lemmy.zip
