I agree Ruby is a cool language with all the features you mentioned.
While it may be true that the culture in Ruby world is to "write good code", I kind of doubt that statement in the real world. Probably only a handful of Rails developers that actually stay true to that culture. The rest just want their share of web 2.0 fame.
Sorry if I'm being skeptical. Maybe cause I saw a lot of Rails blogs that don't reflect the Ruby/Rails culture.
