So far it seems that the admins will make posts when they’re considering new ones. I think the need for committed moderators may be the challenge for adding new ones. You could always find a community on a different Lemmy instance or create a community on an instance that has that enabled.
Such a valid point; success should not be measured only in dollars. I began explaining the basics of the Fediverse with some of my friends and the first question they asked was, “How do people even make money on there then?” It’s a bit disheartening to see how money-driven things are for some people.
