I don't know if there's a solution but in my mind the problem is 'likes' or 'retweets'. Most networks create an incentive to angle only for those at all costs (how else does one become an "influencer"?)--whether it be saying something ridiculous or not. This is one thing that snapchat never did that I appreciate. It's really unhealthy for people because it's essentially like a social credit score (spread across many posts) that anyone new will look at. If you can build a social network that avoids that I think people would be much happier. Also there are lot of people that still want to share content but not participate in that disingenuous ecosystem (or who don't have time) so building a platform for them might be useful.
We already have those social networks. They’re called forums. (I know some introduced likes but they don’t mean much, since your post is still just as likely to be seen as everyone else’s.)
