I do, the star mapping sofware at the core of my company is Common Lisp run by sbcl. I use it because it is fast, reliable, and a pleasure to develop with. Actually, that is true, but the actual reason I use it is that many many years ago I read PG's "On Lisp", and was blown away by it. So I had to find a project to try Lisp out. It ended up being my livelihood.
