Thanks for recommending that essay. Reading through it I found myself first agreeing, every other attempt sings about Lisp's wonders without showing you the what/why/how, only woo. Then, here I was halfway through this essay also not yet knowing what the fuzz is about, and when the author finally gets around to it I end up not really sold on it. I have given Racket and CL my time before only to end giving up, not having found "enlightenment" or even the motivation to keep at it. Another day, with more free time I expect I'll give Beautiful Racket also a try.
