Developers using many major frameworks/languages don't need to quote a single or even a set of "gods" of the framework/language to back up their point. This is one of the problems in Rails, imo. Everything is still about following celebrities like sheep. That is a bad road, my friend. I would much rather live in the midst of a thriving city or within a growing town that had promise than within a hippie cult commune (regardless of its size or the quality of its food or company). Think for yourself. What would you like to use, and why?
I think Rails 3.x continues to live up to that gospel. You're right that Rails 3 is more complicated than Rails 2 (although it is also much cleaner than Rails 2), which was more complicated than Rails 1. However, the world of web development is also steadily more complicated. There was a time when knowing how to create a webpage with CSS put you at the forefront of web technology. That time is long gone.
