I remember when I was trying to start learning Common Lisp, I found it a little difficult for the lack of a resource similar to these. Eventually I stumbled upon PCL and LispBox and managed to take some baby steps. So kudos to the author.
I put together learn-clojure.com (the site in question), for exactly this reason.
There is endless technical information all over the web about any language with even the minor popularity; but when you're stepping in to learn a new language, a short ("curated" in the 2010 vernacular, ugh) list of the most relevant learning materials is much more useful than a reference site or a search with thousands of results.
I found the best route for me was Emacs, the Emacs Starter Kit and Leiningen. Everything is evolving so quickly that I didn't find a decent set of instructions for setting up Emacs manually that worked for me.
The learning curve is bit steep but the tools really are great once you get the hang of it.
