Ask HN: Clojure best practice for web applications?

Does anybody here have experience building a web application using Clojure?

I would like to be able to set up a mysql driven web application using clojure as the language to build it in, but I don't know where to begin to look for the 'best of breed' components to do this with.

This is my first foray in to the big and scary world of functional programming, a trial project to be followed by a much larger one.

Any pointers in the right direction would be greatly appreciated.
