<p>I think the most interesting data would be negative feedback on questions that received more than a few up votes. This tells us that the question was awesome during the time it was in 'circulation', however something has probably changed since then.</p>

<p>It could be any number of things:</p>

<ul>
<li>The question contains links that are now broken</li>
<li>The wording of the question is sufficient to describe a new problem, but is no longer relevant</li>
</ul>

<p>People might also respond negatively if the answers (in particular the accepted answer) have similar characteristics.</p>

<p>It would be great if we could get these in front of people who have tag badges (or a reasonable amount of up-votes) in the related tags. As <a href="http://meta.stackexchange.com/questions/98630/anonymous-user-feedback-now-in-testing/98634#98634">Ian suggests</a>, this could become part of <code>/review</code>, or maybe a <code>/spring-cleaning</code>?</p>

<p>In this particular case, we know that the quality of the post is acceptable, so I'm not sure <code>/review</code> is the best way to present the questions for inspection. We really want the people who can spot and fix subtle problems looking at these, the best way to decide who that is seems to be by votes and badges in any given tag.</p>
