title: Post Facebook Comment with Link Preview via Facebook API
body: <p>Facebook recently added link previews to user comments.</p>

  <p>My question: is there a way to display this link preview using any of the Facebook APIs and publish_stream permission? (Graph, rest, etc)?</p>
  
  <p>I've tried posting a URL in the body of a comment using the Graph API /comments endpoint, but no link preview is shown.</p>
  
  <p>The feature might still be too immature to allow this, but I'm wondering if any one has tried it and got it to work in some way.</p>
