Why can't I both upvote and downvote posts/comments?
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.
This is true for communities that count upvotes and downvotes as +1 and -1 on a single score, but there are plenty of instances where upvotes and downvotes are totaled as two different scores. Not voting gives no response to the original creator, but double-voting like what OP is suggesting would provide +2 total interactions for users on the latter communities.
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
And while we're at it, why is voting only one-dimensional? We should be able to vote a post to the left and right as well, to fully control where it is on the screen.
