dump.fm is a live image chatroom for visual conversations, written in Clojure by Scott Ostler and Tim Baker. Since its start in late 2009, it's become a home for internet artists and their work. It was presented at the NYTM, used as a live image feed for concerts, and showcased by dump irl, an exhibit of art pieces made by dump users.
Scott gives an experience report of building and running a web site with Clojure. Topics include what worked and what didn't, Clojure as a prototyping language, growing a community on custom software, and keeping a side project healthy.
