Very detailed and hands-on Rails Tutorial!

Great job! Im learning Rails, and found your tutorial to be one of the most detailed and hands-on guides. Besides many details of Rails, it also taught me about Git, Heroku, RSpec, Webrat, and most important (at least to me), it emphasized the Test-Driven Development (TDD) methodology. I learned a lot from your tutorial. Keep up the good job! Thanks so much for sharing it.

Ruby on Rails Tutorial is the best!

Just wanted to say that your Ruby on Rails tutorial is the best! Ive been trying for a while to wrap my head around Rails. Going through your tutorial, Im finally feeling comfortable in the Rails environment. Your pedagogical style of gradually introducing more complex topics while at the same time giving the reader the instant gratification and a sense of accomplishment with working examples really works for me. I also like the tips and suggestions that give me a sense of learning from a real Rails insider. Your e-mail response to a problem I ran into is an example of your generous sharing of your experience.
