The gist for those wondering if they should watch this half an hour long talk: it's meant to be funny. You'll probably learn nothing about Clojure or any other technology.
I don't know if nothing is the word. I never used Clojure before and just noticed the REPL takes 5 seconds to start here ;)
Did anyone else find the macro at 13:05 kind of enticing? Obviously the name is tongue-in-cheek, but it felt eerily like something I'd be happy using.
