I use it a lot for my one man projects; it is really fantastic in that setting. I use SBCL exclusively; it is very fast and robust and has image based development. I have my own versioning toolkit so I don't go insane.
It is obvious why it is not really used or recommended as it really falls flat in a team setting, mostly even when 2 people are involved. But fixing bugs live as they happen and then spitting out a new .exe for clients is still a lot faster than modern alternatives. Far more dangerous too.
What makes you think it falls flat in a team setting? There are plenty of N-pizza-sized teams successfully using Lisp to this day and you're probably aware of many teams successfully using Lisp in the past, too. There's also the success of Clojure. What's required to have a well functioning team is mostly programming language independent; Lisp itself won't save a team lacking those properties anymore than say Java would.
