title: Reddit-style nested/threaded/indented comments for Rails?
body: <p>I'm wondering if someone has already built a system for threaded comments (for lack of a better term) in Rails or if I need to build it myself. </p>
  
  <p>In case it's not clear, what I'm referring to is a comment system like Reddit's that automatically indents replies so that they appear like branches of a tree (preferably with voting just as Reddit does). </p>
  
  <p>If someone could point me to code that does this, it would be greatly appreciated. </p>
  
  <p>Or perhaps there is an open source project that includes this functionality. </p>
  
  <p>So far I have not been able to find one in Rails. </p>
  
  <p>Also, would it be better to ask this on a Rails forum and, if so, which one? (I'm new to Rails)</p>
