<p>I am a little hesitant to write this "answer", but let me explore a question of a slightly broader nature.</p>

<ol>
<li><strong>Tagging</strong>. In my view, a tag should be indicative of the subject matter and we should avoid so-called "meta tags" (e.g., <a href="https://stats.stackexchange.com/questions/tagged/homework" class="post-tag" title="show questions tagged &#39;homework&#39;" rel="tag">homework</a>) insofar as possible and reasonable. I've seen the resurgence of a couple that seem borderline cases of this recently. I recommend asking yourself the question: <em>Is it likely that a user would come to this site and want to learn everything they can about <a href="https://stats.stackexchange.com/questions/tagged/x" class="post-tag" title="show questions tagged &#39;x&#39;" rel="tag">x</a>?</em> If not, then <a href="https://stats.stackexchange.com/questions/tagged/x" class="post-tag" title="show questions tagged &#39;x&#39;" rel="tag">x</a> is probably a poor candidate for a useful tag.</li>
<li><strong>Retagging old questions</strong>. This can be a useful community service, but it needs to be done with care. Like anything, when taken to its logical extreme, it can be disruptive. We had just such a case of this about a year ago when an active user unilaterally created a tag and retagged somewhere between 60&ndash;100 questions in a single sitting with this tag (which, to boot, was essentially a "meta" tag). It unfortunately generated one of the more acrimonious exchanges on <a href="http://meta.stats.stackexchange.com">meta.stats.SE</a> that I've seen and the retagger ended up leaving the site over it. My thoughts are that if you're going to retag several old questions, please get community input if it requires the creation of a new tag, and please try to do it during "off-peak hours" as much as possible.</li>
<li><strong>Persistent editing</strong>. This leads in to a related item. Many of us naturally suffer from cases of <em>perfectionicitis</em> (inflammation of the <em>perfectionix</em>, an organ that has apparently developed over fairly recent human history). Some cases are more chronic and/or acute than others. Thankfully it is nonfatal. When making edits, we need to keep in mind the residual consequences and be respectful of other users and the space on the main page. Try to condense and collate edits as much as possible. If you're going to make an edit that is substantial, (<strong>a</strong>) think it through as carefully as possible first, (<strong>b</strong>) look at what else on the page may need to be updated and (<strong>c</strong>) make all the changes in batch. I've noticed a somewhat recent uptick in cases of the same questions rising to the top 4, 5, 6, 7, or even more than 10 times over the span of a few days with several separate edits to an answer, later a title change to a question, then later adding (or removing) a single tag to the question, etc. <strong>This can be (largely) avoided with a little extra planning and with no real drawbacks to content creation and management.</strong> Taken to <em>its</em> <a href="https://math.meta.stackexchange.com/q/4652/7003">logical extreme</a>, it can generate significant discontent that is unnecessary and completely avoidable.</li>
