I don't know Clojure (not sure how expressive it is), but for a framework isn't the code too less? I have seen other frameworks, but they are quite large (in terms of LOC.) Is it that they contain more functionality?
In a nutshell: Make small simple things even if thats ends up beeing a bit more verbose then if you would have built it as one thing. If time shows that a set of librarys works very nicly together then you can write something new that combines these in a nice way.
This is what the Noir does it just pulls together some librarys and delivers them in a nice package.
