The lisp community has a rap among non-members to be full of smug bastards. Actually it is just all the copies of Paul Graham floating around because of functional arguments.
I really wanted to like CL, but the smug inadequacy of its (free) implementations, the awkward holes in every facet of the standard library, and the pigheaded refusal to act as a client of my actual OS instead of pretending to be a separate, incompatible machine…were just not worth fighting with anymore. I'll stick with development platforms that still care about practicality and usefulness, tyvm.
