Yeah I agree this is pretty scary. Two of my clojure projects on github are from when I was learning the language. I'm much better at clojure now, but the public facing code is junk because I was in proof of concept mode, not fluent, idiomatic mode.
I'm torn. Do I leave it up there to show that I enjoy learning new technology in my free time, or do I take it down because it's not coded in the professional quality I hold myself to at work?
Leave it up.I think the fact that you're the type of developer who goes out of his/her way to learn Clojure trumps the fact that it might not be the highest standard code.
I agree with philangist. 99.9% of people that apply for web dev jobs don't have clojure experience. Worst case scenario put it in the README that these were projects from your early understanding of Clojure.
