I run my own instance and I have created some communities that I loved back on Reddit. I searched and no similar communities seem to exist in the fedeverse yet. Obviously there is nobody visiting them right now, so how would you go about trying to promote it to attract some discussion?
Honestly just create them, and don’t leave them for dead (give them content). That way they show up in searches on peoples instances and places like https://browse.feddit.de/
You could promote it on !wowthislemmyexists@lemmy.ca.
Make some good content and release on Lemmy first. Then crosspost to other platforms citing the Lemmy source.
You could promote them in !wowthislemmyexists@lemmy.ca
Or post them to reddit. Some subs are actively asking themseld if and where they move. Of course only the willing part, but a simple: “I created this community, see yea” could be enough
You can try posting them on newcommunities. https://lemmy.world/c/newcommunities
Just remember to post them so that we can all get to that community from different federated !newcommunities@lemmy.world
