Can't undo upvote on comments. The comments area understandably has a small interface and I accidentally upvoted the wrong comment. Apparently they cannot be un-upvoted.

    It looks like this finally got implemented :)

    Although you only seem to have a few minutes to un-upvote a comment. It's happened on several occasions now where I've upvoted a comment very soon after it has been posted. However, the OP has then edited their comment - to which I received no notification or visual indication (as there were no additional comments) - and had completely changed the meaning of their comment. I would have retracted my upvote if I could but unfortunately my upvote was now stuck, showing support for a statement that is utterly wrong.

  • The referred request was to limit time to un-vote for 1 min, but this request is to not restrict it at all. Feb 27, 2021 at 23:25

Oh, no! Now you'll have to forever bear the shame of having anonymously upvoted a comment, which has little to no impact on anything whatsoever!

Seriously, though, I agree with you. It's not high on my list of complaints (why am I still unable to remove a vote to close), but it's on there somewhere.

    I think the remove a vote to close is more important... Aug 3, 2009 at 14:44

    little or no impact - yeah that's why they implemented the feature. Jul 10, 2019 at 14:57

    I use upvotes as a reminder to my future self that the comment adds to the answer. If further down the line I realise that the upvoted comment is wrong, it leaves a wrong message (to me and to anyone looking at a highly upvoted comment). So I wouldn't say it has little to no impact.

On a similar note, I wish there was a way to downvote a comment.

If a commenter puts "the best way to access elements in the HTML page is to use document.all" I can't downvote this. I can post a comment pointing out why it is wrong... and hope for upvotes... but the comments were never designed to support a hierarchy... thus later when someone sees the "minified" comments (based on votes) all they see is a rant that has nothing to do with the original question / answer. :-(

    I sort of disagree... because it works well enough now, and I wouldn't want to complicate the UI. Bad comments usually get shot down by a follow-up comment with many upvotes. (What you say about the "minified" view is true though...)

    By the way, there's a request about this: meta.stackexchange.com/questions/3615/…. And another one: meta.stackexchange.com/questions/7014/…

    @Jonik "because it works well enough now" - the everlasting argument of the mediocre ;) Jul 19, 2019 at 13:44

Considering that comments up-voting will add only +1 to the score and will not influence on what answer will be selected as a right answer, I suppose there is no need in such functionality. Owners of SO may have another vision, but I, as user of SO, don't see any real value in it.
