To me, JSON can be viewed as slightly enhanced S-expressions, enhanced in a particular way. It would sound strange hearing "shoehorning everything into S-expressions in Lisp that is already solved by structural Fortran syntax seems illogical". NIH claim is probably valid when there are no noticeable difference. In my opinion, XML differs a lot from JSON, particularly when one need to write snippets by hand. JSON also seems more logical/laconic (once upon a time M-expressions were supposed to come to stage, but S-expressions turned up to be good enough).
