Clojure - Functional Programming for the JVM

Maybe this has been asked before, but what the hey:<p>Is anyone here on HN using Clojure for commercial production code - websites or otherwise?

This is a great reference, better than the clojure.org website.

Not really news, but I'll take it. Clojure's been popping up everywhere lately and I'm currently knee-deep in functional programming in my PL class, so I'll definitely bookmark this for when I feel like learning over the summer. Thanks!
