title: Real-world Complex Rails applications?
body: <p>For my self-education purposes, I would like to investigate the code of a complex Ruby On Rails (preferably 3) business application(s) so that I can get the feel of how to do things in the real world with Rails.</p>
  
  <p>There are tons of "another blog" or "another CMS", but I am really looking into a Rails app with pretty high complexity (in terms of business rules), but not only the CRUDs.</p>
  
  <p>Something like Real-estate systems must be complex enough. Or maybe in the government area (which is always complex by definition :) ).</p>
  
  <p>Thanks.</p>
