Can't find anything very current, but if you look at names here, Backtype, flightcaster, Runa, there's a lot of info. Best is to hit a user group/meetup or start one:

I started writing a comment but it went Yegge on me so I put it here: http://tech.puredanger.com/2011/10/20/real-world-clojure/

Not a lot of detail here, but lots of folks using it: http://dev.clojure.org/display/community/Clojure+Success+Sto...

Hopefully this will get more people interested in Clojure; more and better content should follow.
