<p>Our usage guidance for the <a href="https://stats.stackexchange.com/questions/tagged/r" class="post-tag" title="show questions tagged &#39;r&#39;" rel="tag">r</a> tag is nice and clear: </p>

<blockquote>
  <p>Use this tag for any <em>on-topic</em> question that (a) involves <code>R</code> either
  as a critical part of the question or expected answer, &amp; (b) is not
  <em>just</em> about how to use <code>R</code>.</p>
</blockquote>

<p>This advice is not part of the text for the other software-specific tags: <a href="https://stats.stackexchange.com/questions/tagged/sas" class="post-tag" title="show questions tagged &#39;sas&#39;" rel="tag">sas</a>, <a href="https://stats.stackexchange.com/questions/tagged/spss" class="post-tag" title="show questions tagged &#39;spss&#39;" rel="tag">spss</a>, <a href="https://stats.stackexchange.com/questions/tagged/jmp" class="post-tag" title="show questions tagged &#39;jmp&#39;" rel="tag">jmp</a>, <a href="https://stats.stackexchange.com/questions/tagged/excel" class="post-tag" title="show questions tagged &#39;excel&#39;" rel="tag">excel</a>, <a href="https://stats.stackexchange.com/questions/tagged/tensorflow" class="post-tag" title="show questions tagged &#39;tensorflow&#39;" rel="tag">tensorflow</a>, etc - these just mention what the software is and who makes it. Would it be helpful to have text similar to the <code>R</code> guidance for these? I can edit them if this is worthwhile. </p>

<p>(I made an edit suggestion for one before realising it was a common issue, and that I should raise it here before editing several)</p>
