I used Erlang at work for coordinated network load testing and it was perfect for that because the problem was well within Erlang's "sweet spot" of "doing distributed communication oriented software correctly". I find Clojure MUCH better for code that needs to do something complex on a single box with several threads (this is a more common scenario).
You are ahead of the curve because you know Erlang and this will help you spot the problems in which it really shines. What do you thing Clojures real "sweet spot" is?
