title: SockJS or Socket.IO? Worth to recode ajax-based page?
body: <p>Which one's better: <a href="http://socket.io/#home" rel="noreferrer">Socket.IO</a> or <a href="https://github.com/sockjs/sockjs-client" rel="noreferrer">SockJS</a> and what are the biggest differences?</p>
  
  <p>How difficult is it to rebuild a completely ajax based page into a node.JS / socket.io based page? Do I have to recode absolutely everything?
  Are there any good tutorials on how to do this? Is it worth to do it (in your opinion)?</p>
