Rails Tutorial (and Railsspace w/ Aurelius) are what I used to learn rails. Your teaching style and practical implementation worked where other resources didn't. Thanks so much for not only releasing this but continually revisiting it and keeping it fresh.
It's also super refreshing to see the changes made to the TDD approach in this revision. I run a small community coding programme for people new to programming and whilst we love referring to Rails Tutorial (among other things), the students often get massively disheartened when they have to face the dreaded wall of testing before they can actually produce something tangible. I completely get the merits of TDD, but I definitely favour the 'produce something interesting, get excited about it and then revisit it and understand how it works' approach for newer students.
