At the request of John McCarthy, Lisp’s creator, no single language that is a member of the Lisp family is to be intended to be the definitive dialect; that is, none is to be called just “LISP.”

So much innovation has happened since the CLHS that to put up a fluff site feels like an effort of "resurrection". When in reality the Lisp family has continued to evolve since then. To limit yourself to just CL, as I did, for a long time, results a bit of a 'losing my religion'. You'll be confounded by things long since solved, and in the end perhaps write all of "Lisp" off. Do yourself a favor and keep and open mind to the family, and not one common incarnation that predates some developers.
