That being said, with a lot of the Clojure IDE plugins and build system reaching usable maturity, the n00b experience has gotten a lot better than when I started a year ago. So, keep up the good works, guys....
True fact: there aren't very many Windows users who are willing to help with portability issues. Of course there's a chicken and egg problem here to be sure, but if you'd like the situation to improve, you should volunteer.
(A great place to start would be by updating the .bat file that comes with Leiningen to work with version 1.2--hint, hint.)
I empathize with your pains, but you can't walk into a biker bar and ask for filet mignon.
Well, Windows users should switch, but failing that, they should be pleased...
Besides, most Windows devs are allergic to anything that doesn't come on an MSDN disc anyway.
It'd be wasted effort, and the communities are smart enough to know that.
(In some ways, the very expressiveness of LISP creates a this cacophony of ways to do things, but that's a post for another day....)
