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.
You already can. Not voting will add 0 points to the counter exactly as mich as adding 1 up and 1 downvote would.
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.
