also, do you have any references or examples of how exactly you use immutant? I looked into it but it seemed to complicated for the webapp I wanted to write, so I went with Hoplon instead. But immutant looks really powerful... I just can't imagine how I would take advantage of it.
some libs we use:
* immutant http://immutant.org/
* prismatic's plumbing https://github.com/Prismatic/plumbing
* korma http://www.sqlkorma.com/
* friend https://github.com/cemerick/friend
* metrics clojure: https://github.com/sjl/metrics-clojure/
