I disagree completely. Playing with existing apps is an excellent way to see how code works, step through it, modify it, etc.
Besides, as I said, I've done plenty of the "scratching my head" and I'm ready to move on. Yes, there are plenty of resources for learning rails, but as I also said, they barely scratch the surface of a real-world application. I understand "Hello World" and I'm ready to look at some real code.
I do appreciate the link, but http://rubyonrails.org was where I started on day 1. I'm looking for a little more depth.
