I am guilty of upvoting it. Five seconds of thinking before upvoting would have prevented me from doing so - the linked comment just doesn't support the headline and Microsoft being hostile/oblivious to open standards isn't such big news anyway.

My point is that maybe we should be able to cancel upvotes. This would give upvoters the chance to read the comments (shallow stories usually have some comments pointing out that they are not that interesting) get convinced that they made a mistake and fix it.

Well, I understand that this might not be as simple as decreasing the counter. I suspect that there might be some impact on the ranking algorithm and probably a dozen things I haven't thought about. Still it might be worth it.
