There was a post here about a year ago that summarizes this pretty well[1]; I've honestly gone back to read it a few times for my own projects as it offers some good perspective and framing.

To some extent, more people can make up for it. Eg if I go from 10 excellent artists to 1000 good ones, chances are that the top 10% artwork created actually gets better.

Then it was for kids from all schools. Then young people. Then their parents too. Clearly, it’s far from dying in absolute terms, but it’s certainly no longer what it initially was. To many initial users, it’s as good as dead though.
My attempt at a solution is to keep it in request-access beta and do targeted advertising only at people who share interests with high-quality subset(s) of discussion on the site, so the new users usually see and can learn what high quality discussion looks like on the site even if all areas aren't mature.
As the site matures you can naturally let more people in until a quite open beta, then full release trying to never take on more than say 10% of the daily active users in any given section/hashtag-cloud per year.
This is my “X can restrict who they deal with” (where X is school or church or business or group or whatever) “but the DMV and the police have to deal with everyone” rule.
