I write Clojure every day and enjoy it. I think Hickey/Nolen have clarified many ways of thinking about programming problems for me. I've learned a lot from them.

But this level of marketing spiel can be off-putting -- especially when you provide examples that non-web architectures have been using for many years.

Imagine I'm an experienced developer, and you've promised that I will be able to express previously unthinkable thoughts if I just learn what these guys are talking about. And then I look at it and it is exactly the same thing my colleagues and I have been doing for years in Java. What am I supposed to make of it?
