Neat. I wish I could find a job that used clojure. To overuse a cliche, I know enough to be dangerous but not enough to be deadly. There is a ton of awesome work being done in the language and it would be fun to really learn it via hard problems.
I lead a team of 4 at a company in the Philadelphia, PA suburbs. We'll be adding more members later this year and Clojure is our primary back-end language (we also use Ruby and lots of JavaScript). We have been quite happy with it for many of the same reasons Alex mentioned.
I recently helped a friend get a Clojure job. I think there are good opportunities if you're looking.
I am still deeply embedded in undergrad for a year or so, so it's more of "that would be nice someday to do" then a "I hate programming all day long in python" type situation. I'll probably try making a real/useful project with clojure before I start looking around the market for sure though.
You can make a problem harder than it looks if you want to :)
