title: Check for new comments in a post instantaneously and add it into div without refreshing page
body: <p>I found a tutorial to add comments with the use of ajax <a href="http://vortexdev.netii.net/article_12/Ajax_comments_system_with_jQuery_and_CodeIgniter" rel="nofollow noreferrer">here</a></p>
  
  <p>Got it working but noticed that you need to refresh page to see comments of other people beside yourself, how can you check that if someone adds a comment you see the comments instantly without the need to refresh the page like what facebook does.</p>
