title: tweet specific blog post link not working
body: <p>I'm using the following code for readers to be able to tweet a specific blog post-</p>
  
  <pre><code>&lt;a expr:href='"http://twitter.com/home?status=Reading " + data:post.title + " @mytwitter " + data:post.url' class='twitter'&gt;&lt;/a&gt;
  
  .content .share .social ul li a.twitter {
      display: block;
      width: 26px;
      height: 26px;
      background: url(img/twitter.png);
      text-indent: -99999px;
  }
  .content .share .social ul li a.twitter:hover {
      background: url(img/twitter-hover.png);
      background-position: 0 0;
  }
  </code></pre>
  
  <p>The link isn't working, and doesn't even appear to be active and I'm not quite sure why. Any ideas?</p>
