title: How to embed interactive content on facebook?
body: <p>I'm interested in sharing embedded content on social media.  My goal is to allow real estate agents to share a slide show of a house they're selling, and to this end I'd really like to be able to embed content rather than linking back to it.  </p>
  
  <p>A great example of what I want to do is <a href="https://www.facebook.com/authorstream/posts/10153256361684250" rel="nofollow">here, on the authorStream facebook page.</a></p>
  
  <p>How are they embedding this content? Do they have some deal with facebook?</p>
