Rearrangement of Rails folder structure

Recently watched Robert Martin’s Architecture the Lost Years keynote and

Following Jose Valim’s https://gist.github.com/1942658, I created an app
with similar structure (rather trivial really). Only been working with
it for an hour or so, so far so good.

Thoughts?
