As a booru and ao3 enjoyer I can promise you that a tag based system works perfectly if posters are good about applying consistent agreed-upon tags and users are good about subscribing to tags they like and putting tags they dont like on their PBL. I dont think mega-big 'public square' type platforms will ever achieve this since growth requires chasing the most passive types of consumers who need everything done for them.
