This doesn't appear to be using Hiccup, which is a shame. But the bigger problem is that the JVM/clojure start time. Rich Hickey has even said that Clojure isn't right for scripting.

You could create a nice Clojure static site generator in ClojureScript (using Himera to compile the templates) though.

My questions is of course - Why not Jekyll?

Is this just for people who have a JVM, but don't have ruby on their box, or are there significant advantages other than just the programming language and environment?
