<p>Here is my proposal:</p>

<p><strong>Objective</strong>: eliminate the meta tag <a href="https://stats.stackexchange.com/questions/tagged/big-list" class="post-tag" title="show questions tagged &#39;big-list&#39;" rel="tag">big-list</a>.<br>
<s><sub>The tag would be removed by the method of blacklisting (see slhck's <a href="https://meta.stackexchange.com/questions/120640/what-does-it-mean-to-burninate-a-tag">answer</a>). That means the tag is removed and it can't be recreated (also, it does not trigger bumping of posts).</sub></s></p>

<p><strong>Premise</strong>: minimize bumping of threads while performing necessary actions.</p>

<p><strong>Constraints</strong>: 3 threads would require edition, but they would be accomplished separately (one per day).</p>

<p><strong>Actions</strong>:</p>

<ol>
<li><p>Replace tags in threads which the only current tag is "big list".</p>

<p>The 3 threads are:</p>

<p><a href="https://stats.stackexchange.com/questions/5465/statistics-interview-questions">Statistics interview questions</a></p>

<ul>
<li>replace big-list by <a href="https://stats.stackexchange.com/questions/tagged/careers" class="post-tag" title="show questions tagged &#39;careers&#39;" rel="tag">careers</a> (x23).</li>
</ul>

<p><a href="https://stats.stackexchange.com/questions/2379/what-are-the-big-problems-in-statistics">What are the &#39;big problems&#39; in statistics?</a></p>

<ul>
<li>replace big-list by <a href="https://stats.stackexchange.com/questions/tagged/history" class="post-tag" title="show questions tagged &#39;history&#39;" rel="tag">history</a> (x34).</li>
</ul>

<p><a href="https://stats.stackexchange.com/questions/10680/how-to-not-use-statistics">How to NOT use statistics</a></p>

<ul>
<li>replace big-list by <a href="https://stats.stackexchange.com/questions/tagged/teaching" class="post-tag" title="show questions tagged &#39;teaching&#39;" rel="tag">teaching</a> (x73) and <a href="https://stats.stackexchange.com/questions/tagged/validity" class="post-tag" title="show questions tagged &#39;validity&#39;" rel="tag">validity</a> (x30).</li>
</ul></li>
</ol>

<p><s><sub>2. Blacklisting of the meta tag <a href="https://stats.stackexchange.com/questions/tagged/big-list" class="post-tag" title="show questions tagged &#39;big-list&#39;" rel="tag">big-list</a> by Stack Exchange developer.</sub></s></p>

<p><strong>Edit</strong>:</p>

<ol start="2">
<li>Implemented as per amoeba's answer.</li>
</ol>
