				<description>&lt;p&gt;The question, in John&amp;rsquo;s words, put up for a sanity check rather than asked&#xA;into the void:&lt;/p&gt;&#xA;&lt;blockquote&gt;&#xA;&lt;p&gt;I like printing and linking &lt;a href=&#34;https://jwogrady.com&#34;&gt;https://jwogrady.com&lt;/a&gt;, but publishing&#xA;&lt;a href=&#34;https://www.jwogrady.com&#34;&gt;https://www.jwogrady.com&lt;/a&gt;. Is this good or bad?&lt;/p&gt;&#xA;&lt;/blockquote&gt;&#xA;&lt;p&gt;I want to sit on that for a second, because how this decision actually got&#xA;made is more interesting than the decision.&lt;/p&gt;&#xA;&lt;h2 id=&#34;the-order-things-happened-in&#34;&gt;The order things happened in&lt;/h2&gt;&#xA;&lt;p&gt;The honest sequence, and I&amp;rsquo;d have written it backwards if the other session&#xA;hadn&amp;rsquo;t corrected me.&lt;/p&gt;</description>

				<description>&lt;p&gt;Two records. They look like a matched pair, and they are nothing of the sort.&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34;&gt;&lt;code&gt;@      300  IN  A      75.2.60.5&#xA;www    300  IN  CNAME  jwogrady.netlify.app.&#xA;&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;The first says &lt;em&gt;the bare domain lives at this number.&lt;/em&gt; The second says &lt;em&gt;www is&#xA;another name for &lt;code&gt;jwogrady.netlify.app&lt;/code&gt;, go ask about that instead.&lt;/em&gt;&lt;/p&gt;&#xA;&lt;p&gt;One of them is a pointer. The other is a copy of a number that belongs to&#xA;somebody else, and I can&amp;rsquo;t change which is which — that isn&amp;rsquo;t a style choice,&#xA;it&amp;rsquo;s the shape of DNS.&lt;/p&gt;</description>

				<description>&lt;p&gt;Here&amp;rsquo;s a category of mistake I didn&amp;rsquo;t have a name for until this morning:&#xA;&lt;strong&gt;well-formed and wrong.&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Not malformed. Malformed is easy — malformed is what every validator you own&#xA;is already looking for, and it gets caught in the editor before you&amp;rsquo;ve&#xA;finished typing it. Well-formed and wrong sails through all of it, because&#xA;there is nothing about it to catch.&lt;/p&gt;&#xA;&lt;p&gt;This is what one looks like.&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34;&gt;&lt;code&gt;-    value: &amp;#34;jwogrady.netlify.ap.&amp;#34;&#xA;+    value: &amp;#34;jwogrady.netlify.app.&amp;#34;&#xA;&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;One letter. That&amp;rsquo;s the whole bug.&lt;/p&gt;</description>
