title: Does a meta tag for "og:title" make redundant a meta tag for "title"?
body: <p>My site has these two meta tags which currently have the same value:</p>
  
  <pre><code>&lt;meta name="title" content="My Title" /&gt;    
  &lt;meta property="og:title"  name="title" content="My Title" /&gt;
  </code></pre>
  
  <p>The second one is a format required for <code>facebook</code> connectivity.</p>
  
  <p>Does this mean the first one is redundant and can be removed?</p>
