I'm not so sure. Most of the Common Lisp people I've met know Java. I can't think of a single one who doesn't know C. Or did you mean Common Lisp people tend to have only that language as their LFSP, no matter how many LFMs they know? In that case I would agree - I definitely see CLers ignoring Ocaml, smalltalk, etc. For my part I guess it's because CL took a long time to learn fully and I need to build up some energy before I invest that amount of time in another LFSP.
