My naive reasoning of why is that a lot of people start by learning c-like languages and don't see the need to learn something as different as lisp. As lisp and it's descendants were never really the dominant language, it was never the first type of language most people learned. Now that many mainstream languages have progress to incorporate more and more lisp features, it's becoming less foreign to many devs and the popularity is increasing and is now higher than I think it ever was.
