I’ve observed this too, though I’m still slogging through tutorials (though I’ve been moving perpetually for the last two months, so I haven’t had time to dig in deep) … but as I’m learning Rails, I’m becoming a better web developer.
I’d already figured out the V part of the MVC with Smarty, and a little bit of the MV, but hadn’t fully separated those out b/c I wasn’t thinking in that pattern, I was just sort of evolving to it — learning Rails is like hitting fast-forward on the learn-as-you-go approach to web development. 🙂
