Search engines are already judging content quality by dwell time and many other factors. Do they have perfect judgement, no. As long as we have centralized search engines than we have specific judges of quality.

We used to live in a world where the pagerank would be an indicator for quality. Yet, as we are now accessing the web through a pre-filtered aggregate on Twitter, Facebook, Reddit, and also YN, the use case for Google has fundamentally changed

Exactly, bro. Quality is subjective, so it's up to the owner of the website to determine the quality of their own content based on their own standards and goals.

Disagree, the search engine needs to make the judgement on the quality.

As a user doing the search, I can't trust the opinions of the website owners, but I have to trust someone. I want to trust the search provider, particularly because I can easily switch if I choose.

yeah search engines better judge the content right. they better use the right signals, like metadata and user engagement, to give users what they want.

and website owners better do their part too, by tagging their content correctly and putting out only the highest quality material.
