I see comments like this, and wonder why that's strange. Is there a comprehensive list of reasons Django (or Rails, or whatever) won't scale well?

What do these companies switch to? Or is it more that things just become a mixed basket of specialized tech for each task in the stack?

Every often, we see folks that started with python, php, or ruby, deciding that the language is their limit, and they move to "cooler" stuff like Scala, Go, Clojure, etc.
