I find the Rails tutorial to be a terrible intro to Rails (unless if you're already a web dev, or a crack dev), but a fantastic intro to TDD with Rails. I recommend JumpStartLabs' Blogger tutorial as the best intro to Rails.
Awesome! I look forward to it!
Leaving out TDD would definitely be easier on a beginner—but it would also undoubtedly make him dangerous.
I would think the opposite actually: learning TDD often gives people a false sense of safety.
I think Rails For Zombies is great for 'instant gratification' in the same way as the old 5 Minute Blog Tutorial used to.
