Ask HN: How would you design an alternative Twitter
I think you're jumping into the technical bits right away without thinking through requirements/features. Maybe we (the royal 'we' as in all of humanity) shouldn't have a public town square?  When you build something to have marginalized voices be heard you are also including <i>all</i> marginalized voices.  The MarginalizedVoice super object has EqualRightsForSquirrels as well as HatefulRacistUncle child objects. There are very valid points, that people don't like to hear, about how the concept of someone/group choosing what MarginalizedVoice gets heard and what doesn't isn't fair. If the basis of a platform is "public town square" you're going to have to deal with <i>all</i> MarginalizedVoices.<p>Content moderation (incl comments)  doesn't scale so don't build something with public town squares.  That's only a feature platform builders want in order to sell advertisements. If the thought of not having an ad-driven platform leads you to "users won't pay for it" then maybe think of a platform users would pay for or some other way to have it be sustainable.
