      Here's one bank that is blogging about moving to Clojure:
      http://www.pitheringabout.com/?p=778

      It is used in a few places, but its not common. The reason it isn't used often is because no one bothered to build anything with it. So, if Clojure / Lisp / etc want to make the language popular, you should build something that makes money and tell the world about it. This is what happened with RoR and Django.

      I have a CRUD site written in Clojure. All total is around 1,500 LOC. I only have to add in a mailing feature and and one other small operation and take it off the now-deprecated Noir framework. All told, it will still be 1,500 LOC, I think. It takes in quite a bit of information, has multiple "views," dynamically generates HTML, connects to a database, and allows quite a few unique operations, so it's actually very easy to create a website in Clojure, and it can be highly elegant once you get used to the data structures and how to destructure.

      The Clojure community has done an excellent job to make the process of building -> deployment very easy, it's just that no one has stepped up to the plate and did anything with the tools, and unfortunately, I fear Lisp will always be a Land of Toys and No Product Shipped.

      This is the third of a series of posts about introducing Clojure at an investment bank.

      The first and second posts are here

      Tangentially, the 'swedish colleague' the author brought in to help with the transition to Clojure is the immensely talented Hakan Raberg (sorry don't know how to type umlauts etc on my keyboard) , who is a good friend and worked with me at ThoughtWorks before he went indie.

      > Was it the lack of structure that made them go for it in the first place?

      Here are the first two posts that discuss their decision:
