@brianjlandau correct me if I'm wrong, but I believe that we ended up removing the nesting because that way we don't have to pass the comment any data about the article or comment that is being replied to. When the routes are nested like that it requires a lot more data to be stored in instance variables and passed as a parameter. In the end I think it smoothes out the code to do it this way. We tried the nesting style for a while and it was causing some issues.
