I beg to differ. I've used ClojureJS (a Clojure to JavaScript translator) for building a non-trivial web app front end, and the result has not only been robust but also a pleasure to build (from a Lisp programmer's point of view).

Interesting. What's the site, and is the original Clojure source before -> js transformation published somewhere?

We're not launched yet (but, close). I'll definitely post about it when we're live. I'm not sure how much of the Clojure (subset) code we'll publish, but I'll write more about our process and experience once we're launched.
