FYIW, we are writing production web apps and server side applications
all in Clojure for several projects. There about 10 developers in my
shop and we all pick the poison of choice. There are emacs users, NB/
enclojure users and Eclipse/ccw users. We use maven for the builds
and git for our scm so that is the comment ground and there is no
issue with opening and working on the projects within each of these
environments. None of them are perfect and they each have their
strong points.
I know that may not answer your question with regards to tools but
Clojure as a platform has been a productive and fun platform for us to
deliver apps and experiment with new technologies in our shop.
