<p><a href="https://stats.stackexchange.com/privileges/suggest-tag-synonyms">You need 2500 rep</a> to suggest a tag synonym.  However, I fully agree with you.  I vote that both <a href="https://stats.stackexchange.com/questions/tagged/test" class="post-tag" title="show questions tagged &#39;test&#39;" rel="tag">test</a> and <a href="https://stats.stackexchange.com/questions/tagged/testing" class="post-tag" title="show questions tagged &#39;testing&#39;" rel="tag">testing</a> should become synonyms for <a href="https://stats.stackexchange.com/questions/tagged/hypothesis-testing" class="post-tag" title="show questions tagged &#39;hypothesis-testing&#39;" rel="tag">hypothesis-testing</a>.  As <em>test</em> &amp; <em>testing</em> don't have tag wiki excerpts to help determine their proper scope, and as they are less utilized, they should become synonyms in this case, in my opinion.  </p>

<p>In general, I think maintaining the optimal organization and usability of the site will require some amount of continuous effort.  Much of the organization is driven by the tags, so they need to be created, merged, and (at a minimum) have tag wiki excerpts to guide their usage.  Unfortunately, I also don't think the synonym suggestion system works very well on CV, because we are a smaller and younger site.  There are relatively few users with the needed rep and number of upvotes on a given tag to suggest synonyms and to vote on the suggestions of others.  Frankly, I doubt that anyone regularly checks the <a href="https://stats.stackexchange.com/tags/synonyms">synonyms page</a> to see whether any are pending and to vote on them.  Certainly, I'm guilty of that.</p>
