At least in terms of the open-source community it feels much more lively now than, say, the early 2000s. There are new books like Practical Common Lisp and Land of Lisp, SBCL has matured into a solid implementation, Clozure CL was open-sourced, and Quicklisp has really improved the convenience of using libraries. I don't know whether that translates to more popularity overall, though.

If you mean the overall Lisp family, I think it's more clearly on an upward swing, especially due to Clojure's popularity (and if you're willing to stretch, Julia smuggles a Lisp-like language under cover of Matlab-like syntax).

Re: open source Lisp, I guess other venues than comp.lang.lisp have taken a lot of the mindshare (the demise of Usenet).

cll was rabidly against OSS, e.g. Pitman's pure hatred for it was practically Gospel there.

A few years ago some younger Lispers emerged, for who OSS was natural, just like with the short Ada renaissance.

At least the "young Lispers" are still there, unlike their Ada counterparts, even if they haven't taken over the world.

+1 for Practical Common Lisp, great book, not as dry and academic as other Lisp books. For comparison, ANSI Common Lisp uses ray tracing as an example, whereas Practical Common Lisp uses an mp3 database.
