I might love a part and strongly dislike the other part of a post or comment. Why can’t I both upvote and downvote? Double tap for a conflicted situation? Why am I restricted to the net of my opinions?
I will try to implement this when I have time, lol time.
Why do you think that you deserve two votes, when everybody has just one?
Even better. Have floating point +ive and -ive votes. You can put whatever value you want as long as the sum of absolute values of + vote and - vote is <= 1. And >= 0 of course
