Thanks James! The only thing I think is missing now are solid libraries (or ports of).
With ClojureScript support there are some interesting applications/possibilities on the client side that I'm just beginning to explore. I would definitely be interested to see what people discover in that space.
Unfortunately, I think it will be a while before others (Sass/Less users) see the benefits and potential of this approach to stylesheet programming. For that it would likely need some mentions from CSS thought leaders and, again, librarie.
FWIW, team Simonides used Garden for our app in the Clojure Cup. We didn't do anything advanced but it spared us one less language!
