I saw lots of 0 point accepted answers on Stack Overflow and it makes me discomfortable, because if someone accepts the answer, they should and must upvote the correct answer. Or maybe, any correct answer automatically gets 5 upvotes?
This makes me umconfortable: https://stackoverflow.com/a/50190833/1944314 a correct answer and no upvote.
There are two possible explanations, if the user upvoted already then it must be someone else downvoted it. So there's one more possible exception.
We must be able to see how much upvotes and downvotes every post has, next to the total 'karma' of that post. After that, we can be sure of the karma of the question; I believe this will be a very useful feature.
I am personally not annoyed by downvotes, but nobody should downvote unless it is positive criticism.
