An article that would title "Lisp beyond Clojure" would indeed talk about the Lisp family of languages. What is a very bad in that title is that it focuses on Racket, just as if the title was: "Racket - this is how Lisp looks like beyond Clojure". And that is the main problem I have with the title. The ideal title would be IMO "What could Clojure learn from Racket".
