title: How to setup facebook stream api
body: <p>I'm currently investigating the possibilities of the facebook (and twitter) streaming api. I read the docs but after doing many google searches I still can't figure out how to get a realtime stream from facebook.</p>
  
  <p>If I know it correctly, facebook let's you subscribe to a stream. When there are new updates facebook does a post request to your callback server and let's you handle that information.</p>
  
  <p>I already found a callback example on the facebook github page. But how do I subscribe to a stream?</p>
  
  <p>And is it possible for one registered facebook app to have multiple users connected to it?</p>
  
  <p>Thanks in advance.</p>
