title: How to flatten nested JSON?
body: <p>Let's say I am dealing with JSON like this:</p>
  
  <p><a href="http://hndroidapi.appspot.com/nestedcomments/format/json/id/4620423?appid=hntoolbar&amp;callback=" rel="nofollow">http://hndroidapi.appspot.com/nestedcomments/format/json/id/4620423?appid=hntoolbar&amp;callback=</a></p>
  
  <p>Which can be infinitely nested.  I want to extract all of the comment information in a "flattened" format, just a list of usernames and the contents of their comment without worrying about the "level" of the comment.  How would I do something like that using Javascript/JQuery?</p>
