title: XMPP/AMQP/Websockets vs Pusher/Beacon push?
body: <p>With Pusher and Beacon push cloud services I can get live updates in all browsers. Even implement chat functionality.</p>
  
  <p>Can't these cloud services replace the need of me learning XMPP/AMQP/Websockets/Comet to implement the same kind of live updates/feeds?</p>
