Here is a shameless plug:

http://www.vixu.com (my startup) is based on open source Clojure/ClojureScript CMS (and soon webshop) software. See https://github.com/fmw/vix for the code (planning some refactoring over the summer before the first official release). Also doing search related stuff in Clojure (see https://github.com/fmw/alida for demo code I wrote for my EuroClojure presentation).

Clojure brought the fun back to software development for me and made me a better developer in general. It is also a very pragmatic choice, with the expressiveness of Lisp and plenty of reusable Java code being available.
