Clojurians Log v2

Hi #code-reviews, I released an image/discussion board recently and someone asked me if they could get a copy to use it for personal use. I said sure, and I've linked to the source code on the about page of the website. I was hoping some expert/pro Clojurians from around here could take a look and offer their feedback on the source code readability, clarity, succinctness, best-practice-ish? and so forth.
