all it does it create an echo-chamber. It’s self-reinforcing.

Totally agree. Also, I'm taking into an account that this is a view of people who have internet -> browse lemmy -> browse or subbed to the community (interested in) -> saw the post -> read comments -> default sort (i believe lemmy's default is hot which is new?) so definitely biased

I also don’t care if other people found a post “positive” or “negative” or “neutral” in general. Truthful, well thought-out comments get downvoted into oblivion despite being true, simply because they aren’t mainstream views. Likewise, mainstream views with no basis in reality get upvoted incessantly, probably because humans psychologically like believing that their beliefs are true and seeing “confirmation” of their beliefs is seen as a good thing. This is what is meant by self-reinforcing echo-chamber: fringe or dissenting opinions get hidden, and “more of the same”/“towing the line” conformity get promoted.

I stated that it's good to know "what people who read this post or comment think of it" regardless of post/comment truthfulness. It's useful (for me) to assess whether many people agree with, against, or it's controversial.

PS: This information wouldn't change my opinion about a post/comment.
