Maybe one of the most difficult things coming into it is trying to relate it to something like BackBone.
However generally speaking in Clojure the culture is more about libraries than frameworks.
C2 http://keminglabs.com/c2/ which on the outset looks just like a ClojureScript version of d3 is actually a great library to use instead of a traditional front end framework.
Check the example implementation of the class TodoMVC list here: https://github.com/lynaghk/todoFRP/tree/master/todo/c2
It's uses normal Clojure data structures within atoms as the data model (https://github.com/lynaghk/todoFRP/blob/master/todo/c2/src/c...) and uses C2 to automatically update the UI (https://github.com/lynaghk/todoFRP/blob/master/todo/c2/src/c...). Very elegant.
I'm just starting to explore this area myself, but have already found it useful for a few smaller parts of our site.
