My $0.02, I was a very early Clojure adopter, but I stopped using it when Oracle bought Sun (I left the JVM completely at that time). I am currently using ClojureScript a lot - for the last 6 months or so, thus not the most experienced programmer.
Most of my usage is doing scientific simulations (genetics and epidemiology in my case). I published one simulator in Scala and Java. Done quite a few in Python+C and currently working in JavaScript + ClojureScript. My observations here come mostly from my Scala work and my current work in JS+CLJS. First observation is that a lot of scientific simulation code is highly imperative (not saying if that is good or bad), so lots of the mentality in the field is geared towards that. Still lots of Fortran floating around, for example. In many cases performance is really really important. This tends to be CPU bound, rarely disk or network. Sometimes memory might be a consideration. My general strategy is to do the computationally expensive core in a lower level language. For example, my Scala simulator had the core written in Java. My ClojureScript stuff has a JS core (and in the future will have parts in C). The Python stuff had C/C++ code. The higher level language (Scala or ClojureScript) provided the interfaces to manipulate the lower level code in a declarative, elegant and functional way (actually DSLish way).
