Probably yes, the former not only "looks better", but is possibly easier to use in a view. Just spawn two delegates with `$post_path` and `pathcat($post_path, '

Probably yes, the former not only "looks better", but is possibly easier to use in a view. Just spawn two delegates with `$post_path` and `pathcat($post_path, 'comments')` and be done with it. However, the argument being made here is that you may not want to expose post comments as sub-resource of a particular post, but rather as completely separate resource. And there is a point to that. Suppose you serve the post content as a static content, and comments from some application (octopress + disqus style). The latter format allows you to route anything matching `^/posts/(.*)` directly at web server level without touching application server at all. If you decided to use the former, then your infrastructure becomes dependent on your API structure. Not very nice :)
