I find this popup very annoying, and will stop upvoting questions if I have to see it every time I do so. Can you please add an option to disable it?
According to the linked question:
In essence, this is a Skinner box. The desired behavior seems to be to encourage upvotes and (potentially) encourage sharing of the question. However, the effectiveness of the response depends on the subject (i.e., you) finding the occasional consequences rewarding.
It seems for you (and me) the conditioning is actually of the positive punishment variety. That means that, whether you plan to or not, you will press the upvote less often than normal now that you've made the connection between behavior and response. You may also find yourself anxious just before upvoting.
Why is the popup a punishment? There are several reasons:
There may be more problems, but for those of us users who are annoyed by it, there should be an option to turn it off. (Or better yet, kill the feature.)
