I believe I heard that reddit has started a different kind of feed to replace r/all and it does introduce some kind of algorithm that "suggests" content differently from the straightforward upvote system. Although the popularity contest aspect of it was always somewhat regrettable, I liked that it was a really simple algorithm that supported an entirely human driven curation of content, so it seems like a regression.

As someone who usually shows up to the thread after most of the energy has moved on, it is always a little disappointing. It seems open for some kind of innovation that could keep the conversation alive and give it the longevity that comment trees generally lack. I always try to reply to these straggler replies to my own comments.
