> understand that a reviewers role isn't to agree or not Humans are universally terrible at doing this. IMHO the only hope is to give them two voting axes, so they can placate their lizard-brain's "downvote to disagree" impulse but still apply a separate but positive expository-quality rating. If you only collect the latter kind of rating it won't work. TL;DR: in addition to thumbs-up/thumbs-down, give people poop-emoji/gold-star. I would hand out a lot of poopy-thumbs-up votes.
