I don't program anything serious with Lisp', just toying around for what seems to be forever (having friends/colleagues that don't program in same language doesn't help - in fact, it alienates me from Lisp even further). Clozure and PLT..er Racket Scheme for me, but if I were to try web development or anything more serious than just toying around I'd definitely go with something JVM based for libraries support, if nothing else.
