Please, check http://cliki.net, http://common-lisp.net and http://cl-user.net. There are packages to all the things commented.

About SQL, for example, I'm using Submarine (ORM) with Postmodern and it's running like a charm. For Web development, there are Hunchentoot, AllegroServe and interesting frameworks like UCW or Weblocks (each one I'm using right now).

Maybe the guy didn't tried enough, more 5 min. at google would be enough ;-)
