It used to be that the best posts would have hundreds of upvotes and hundreds of down votes. They showed +100/-98 and you did mediately knew this was an interesting comment.

Then they stopped showing both up and down, and only showed the summation. 100 upvotes and 98 down votes is now +2, and this comment is now lurking among all the other +2 comments.

Showing the total instead of the ratio was the end of reddiquette, and the earliest Reddit enshittification that I can point to.
