In the 15 years since this was published, maybe it's more accurate to talk about the family of languages, rather than just Lisp itself. I imagine that together all of the Lisps represent a lot more of the language popularity long tail then one might think. Of course this is just a hunch and I have no data. Also, Clojure seems pretty trendy among certain circles these days, which is a Lisp on the JVM (and Python, JS, etc).
