Extrapolating from the post that Clojure tooling is bad seems like a strange conclusion. I'm actually surprised that such a narrow post would find this much interest on HN.

Clojure deploys are pretty ridiculously easy - and refreshing pages on a Clojure based web stack is also instantaneous.

Seriously, Leiningen is great tooling. On pretty much every axis except startup speed I prefer it to everything else I've needed to use for work in other languages (Python, Ruby, and Node.js).
