As of a few years ago, my assessment of the Common Lisp universe was that anyone who once had the energy for standards, promotion, adoption, etc. is now too old, and past their generational energy, to bother with such things.  New generations learn their own things, and although they may use many design ideas of lisp, they're just not going to use Common Lisp for the most part.  For instance, Julia claims some lisp ancestry.  http://julialang.org/
