I am not a Redditor, but RES sounds like it would increase the ‘echo-chamber’ effect, rather than improving one’s understanding of contributors’ calibration.
it depends on if you vote based on the quality of contribution to the discussion or based on how much you agree/disagree.
Echo chambers will always result on social media. I don't think you can come up with a format that will not result in consolidated blocs.
Reddit's current structure very much produces an echo chamber with only one main prevailing view. If everyone used an extension like this I would expect it to increase overall diversity of opinion on the site, as things that conflict with the main echo chamber view could still thrive in their own communities rather than getting downvoted with the actual spam.
More than having exact same system but with any random reader voting ? I'd say as long as you don't do "I disagree therefore I downvote" it would probably be more accurate than having essentially same voting system driven by randoms like reddit/HN already does
Echo chamber of rational, thoughtful and truthful speakers is what I’m looking for in Internet forums.
