if we really want to "scale" the fediverse what we need is more community organizers and more tools for those community organizers.
We get so focused on trying to emulate capitalism that we forget that this space is made of people. If we get community organizers here from every walk of life, then their communities will follow.
People won't leave the walled gardens, because the community organizers were wooed into how easy it is to do their organizing there.
