I get what you're saying. What you are describing is the core fundamental idea behind, what is now, almost derogatorily called "the algorithm".
It's great, in concept, to implement such a system, right up until someone decides to change the way it chooses what you see for the benefit of advertisers.... Which is pretty much what's happened to every social media network, and to some extent, Google searches... Someone decided to cram what was essentially an ad into everyone's faces by manipulating the algorithm, and not "SEO" is being weaponized against the users. SEO as a concept is a way to effectively manipulate the selection algorithm to artificially push your content to the top. It's not a new concept, which is why there are still companies called "AZ construction" and other related names; those business names were largely popular due to the phone book (aka "yellow pages") so when going down the list of companies for a product or service you need, they would be the first name you saw, simply because the phone book was sorted alphabetically.
The enshittification of all of that is exactly the same reason so many of us abandoned Reddit.
