> Robert Morris says that I didn't need to be secretive, because even if our competitors had known we were using Lisp, they wouldn't have understood why: "If they were that smart they'd already be programming in Lisp." [0]
In other essays, he goes on to describe what makes Lisp different [1] but its all fairly technical (example: Programs composed of expressions. Lisp programs are trees of expressions, each of which returns a value.) I've heard professors also wear their Lisp background as a badge of honor.
What's the practical implication of Lisp's unique features, specifically in developing web applications? Is Lisp still being used in web apps?
