Am I interpreting your suggestion correctly that you want to basically hide or do away with voting and instead switch to adding notice plaque / info bubbles / comments about how the post can be improved? If so, that is an interesting idea, and would be a big break from the whole reputation system.
Good posts would not need any requests for improvement, and bad posts would not get downvotes which affect poster morale. Also there would not be an incentive to post “popular”-designed posts to attract upvotes to satiate that internet karma hunger. I would like to explore this concept in more depth if someone else is interested in such an interpretation.
As for my proposition of adding extra “votes” in form of reactions on top of existing voting system I get that it could worsen the emotional response situation in some cases, but I would still like to have that experiment one day. Maybe not in this official version but in a fork.
