Should I be able to cancel my up-vote on a comment?
The above question is closed as status-declined, but I can't find the reason anywhere.
I am not requesting this feature. I simply would like to know what the rationale is behind providing this feature for answers, but not comments.
Given that this is implemented for answers, and the general consensus seems to be that the feature would be beneficial to SO, I am left wondering: why was this declined?
