I'm sure maybe some/ all of us maybe aware, but I've been using this and found it quite helpful in playing around: <http://clojurekoans.com/>
I was given this vimrc, by someone I work with as a starter to working with Clojure. for those who don't have a text editor for Clojure yet, I would heartily recommend vim with this vimrc as a noobs guide. https://gist.github.com/bw-matthew/d52f17294f292135e93f
clojure on exercism might be good too
@voidlily: although I wonder how to get more advice from others in exercism. I learned about 10 new things on the first exercise alone but only because I read other people's code (vs getting comments from others directly on my submission) ... see the asymmetry http://exercism.io/nits/achengs/stats ... the graph is supposed to have a second line for 'nitpicks received' but it's missing because no one has commented on my submissions (except me)
