Nice web site! I have been using Common Lisp since 1983 when I updated my Xerox 1108 Lisp Nachine.
In the last 35 years I have probably only averaged using Commin Lisp for about 10% of my development but still love the language.
One problem the Lisp world has is too many fine implementations of dialects of different Lisp languages. I find it impossible to not experiment with most of them.
