This seems true, but there's also another level to it. If you're a major figure in a community yourself, you have plenty of other outlets to show off and get your message out. Those folks come to posts on Reddit because the audience is there. Maybe they're just cross-posting their instagram posts, but they're doing it because they know it'll reach a decent amount of people that wouldn't see their stuff otherwise. Getting to that point takes time, and it takes dedicated amateurs keeping the community growing, engaged, and excited in the meantime to get it to the point where it's big enough that bigger names care to jump in.
