Not only that, it's noise compared to a few other dynamic languages:

I'm not disagreeing, but to be fair, "common lisp" is often referred to as "lisp" or "CL". So the phrase is good for (down)trends, but not for comparisons.

True, I should have shortened it to just lisp. Here we go:

http://www.google.com/trends?q=perl%2C+python%2C+ruby%2C+lis...

Yep, still noise.

I wouldn't put too much faith in the popularity of languages on Google trends when they have names which are commonly used in english. For me, the headlines on the right hand side say it all:

Jeff Ruby asks OJ to leave business

Ruby on Rails 2.0 Released

JFK Documents Include Reported Ruby, Oswald Conversation

23-foot python found basking in sun

Former Olympic champion Ruby dies in climbing fall

Monty Python reunite

Only one of those is related to programming.

This could also mean that there is neither an opera named "common lisp", nor a comedy group, nor a gemstone fo the same name ... and well perl's fame is waning or fewer people misspell pearl.
