The only reason these tickets are not sold out is because it is a newish conference. This is only its second year. I went last time and it was great: awesome topics, amazing participants, and hands-on workshops and jams. Look at the amazing line-up! There’s still time to register and get your plane tickets. I wish I could go this year, but I have other obligations. This is one of those conferences that you don’t want to miss. It was started by Alex Miller, the man behind Strange Loop and Clojure/West.
