i totally could see reddit attempting something like that especially with the removing awards.
an even grosser implementation would be 2 sets of upvotes and downvotes. Premium vs free ones.. my god it sounds like discord nitro and tinder premium had a baby
To be honest, I've always felt like ratings systems needed a "thumbs sideways" option. Like a "meh" or "it's okay" or even "it's kind of good, but has flaws that bring it down".
Youtube for instance really could use a thumbs sideways button. Many sites that show longer form artistic content that could have varying degrees of quality over time could also use it.
