title: How do I get the Google +1 button to give a preview of the article rather than the top HTML on the page?
body: <p>Google Plus lists all your +1s with a small preview of the webpage that was +1ed. Techcrunch and Mashable's previews come up as the first sentence of the article, however for me it just takes the first HTML on the page (which in my case is navigation). How can I get it to target the article for this preview rather than the navigation?</p>
  
  <p>I have looked through the <a href="http://code.google.com/apis/+1button/" rel="nofollow">API</a> and couldnt find anything that would do what I'm talking about.</p>
