Common Lisp is a member of the Lisp familiy of languages, just like Clojure is.

There are also derived languages like Stella, L, SubL and others which implement some kind of subset.
Then there is ISLisp, which is very similar, but slightly simplified.
Remember, all it takes is one "XYZ sucks" post on the front page to get a front page full of "Why XYZ doesn't suck", "XYZ sucks super hard", "We're using XYZ at my startup", "Successful founders use ZYX, not XYZ", etc.
I'd rather a million lisp stories than all the non development related human-interest/social-studies stuff that often winds up on the front page ;)
Clojure when viewed as a functional programming answer to multicore and concurrency is stunningly beautiful in it's simplicity.
If you haven't read Rich Hickey's prose on State and Identity. I highly recommend it: clojure.org/state
What about real-world usages in large systems?
