I don't think reverting to chrono content makes sense. If popularity doesn't influence what's top-of-feed, then we'll just be flooded with un-interesting content.
Imagine if HN or Reddit didn't sort by popularity? Everyone would need to sort through /new. ...that's not scalable.
What would be better would be to reward controversial content. If lots of people downvote something, and also lots of people upvote, then maybe it needs more attention, not less?
So that rather than creating ever-more-extremist bubbles, people are more likely to see opinions that make them force them to appreciate other points of view.
