title: html code for twitter button is wrong
body: <pre><code>&lt;a href="https://twitter.com/TwitterDev" class="twitter-follow-button" data-show-count="false"&gt;Follow @TwitterDev&lt;/a&gt;&lt;script async      src="//platform.twitter.com/widgets.js" charset="utf-8"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Error parsing XML, line 8, column 133: Attribute name "async" associated with an element type "script" must be followed by the ' = ' character. How do I fix? sorry, I have very little html background</p>
