title: What is the appropriate use of the Article element?
body: <p>I want to change</p>
  
  <pre><code>&lt;section&gt;
    &lt;header&gt;...&lt;/header&gt;
    &lt;p class="tweet"&gt;This is a tweet preview. You can... &lt;em&gt;6 Hours ago&lt;/em&gt;&lt;/p&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>into</p>
  
  <pre><code>&lt;section&gt;
    &lt;header&gt;...&lt;/header&gt;
    &lt;article class="tweet"&gt;
      &lt;p&gt;This is a tweet preview. You can... &lt;time pubdate&gt;6 Hours ago&lt;/time&gt;&lt;/p&gt;
    &lt;/article&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>But after reading some <a href="http://html5doctor.com/the-article-element/">articles</a> on the <code>&lt;article&gt;</code> tag, I'm not sure that this is the best move. What would be better practice? </p>
