Ruby is all about conventions, most Ruby, and by extension Ruby on Rails apps look pretty similar despite the fact that the language is extremely expressive. I don't buy that a staff SWE and a new grad will write very similar code in Go. As far as simple language. It is possible to design simple languages that are very expressive, Lisp and Erlang come to mind.
