<p>I just edited the <a href="https://stats.stackexchange.com/questions/tagged/online" class="post-tag" title="show questions tagged &#39;online&#39;" rel="tag">online</a> tag and noted some synonyms for "online" algorithms. Among them are "dynamic" algorithms, so I looked whether we have a <a href="https://stats.stackexchange.com/questions/tagged/dynamic" class="post-tag" title="show questions tagged &#39;dynamic&#39;" rel="tag">dynamic</a> tag or similar and whether making it a synonym for <a href="https://stats.stackexchange.com/questions/tagged/online" class="post-tag" title="show questions tagged &#39;online&#39;" rel="tag">online</a> would be warranted.</p>

<p>We have four tags containing the word "dynamic": <a href="https://stats.stackexchange.com/questions/tagged/dynamic" class="post-tag" title="show questions tagged &#39;dynamic&#39;" rel="tag">dynamic</a>, <a href="https://stats.stackexchange.com/questions/tagged/dynamic-regression" class="post-tag" title="show questions tagged &#39;dynamic-regression&#39;" rel="tag">dynamic-regression</a>, <a href="https://stats.stackexchange.com/questions/tagged/linear-dynamical-system" class="post-tag" title="show questions tagged &#39;linear-dynamical-system&#39;" rel="tag">linear-dynamical-system</a> and <a href="https://stats.stackexchange.com/questions/tagged/dynamic-linear-model" class="post-tag" title="show questions tagged &#39;dynamic-linear-model&#39;" rel="tag">dynamic-linear-model</a>. From what I can tell, the last three are fine (though the last two could profit from a tag wiki).</p>

<p>However, <a href="https://stats.stackexchange.com/questions/tagged/dynamic" class="post-tag" title="show questions tagged &#39;dynamic&#39;" rel="tag">dynamic</a> is a mess. <a href="https://stats.stackexchange.com/questions/tagged/dynamic">It looks like it has been inserted in questions on specific techniques that happen to have "dynamic" in their name, or in other instances that have something "dynamic" about them.</a> There is no common overarching theme. I don't, for instance, see a way to write a tag wiki, nor do I believe anyone will ever filter on this unspecific tag.</p>

<p>I propose that <a href="https://stats.stackexchange.com/questions/tagged/dynamic" class="post-tag" title="show questions tagged &#39;dynamic&#39;" rel="tag">dynamic</a> should be deleted and blacklisted, AKA burninated, so it won't be misused in the future. Thoughts?</p>
