If that was the only challenge, then why aren't Discourse deploys, reddit clones, or Lemmy instances dominating the social media world? Voat would be an example of a social media site that was spun up without VC interest (it started up as a hobby project from a college student as an alternative to reddit in part because of moderators). And so I return to my question: if it is viable to do without VC funding and the demands of revenue growth - why aren't there more of them out there?
