I've since come to believe that to have a high quality medium, you really need not just the editorial guidelines I've mentioned, but also someone who interprets those guidelines in the intended way, and the ability to enforce them properly. That means you can, at best, have a small team of moderators/community managers, likely with the person who has manifested the editorial guidelines at the top. This does not scale, so the community is limited in size. When I think back to the times of TV channels, professional magazines, radio shows etc., I remember how amazing the quality of that content could be. Reading the same magazines printed back then today confirms that to me. Curated content wins. Sure, some TV channels and magazines were terrible instead, but that's just because I did not agree with their curation.
