This is the "Best Quotes" example application from the book "Rebuilding Rails" by Noah Gibbs. You can find the canonical branch of this framework at "https://github.com/noahgibbs/best_quotes".
It really only exists to give Rulers something to serve up.
The code is still free to use if you want to. I just don't know why you'd want to.
