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?
When I tried to search a community I used this https://browse.feddit.de/. Similar but there’s also this https://lemmyverse.net/
That only pulls up lemmy communities, meaning it misses kbin ones.
