I wouldn't have recommended the rationale if he had asked "Why do YOU care about Clojure." Not knowing anything about him other than his self-confessed lack of effort, I thought it best to point him to some source material, not tell him what suits ME (which he didn't ask anyway). Also, no fair someone else getting karma for posting the link to the rationale. I left it out in hopes that the lazy questioner would lift at least one finger in his quest for Clojure knowledge (no, not THAT finger).
That is to say, the reason for asking a question like this is not always laziness.
