I didn't say anything about popularity. Scheme is arguably more popular than Lisp, and Clojure and other Lisp derivatives are currently on more radars as well.

But Red/Rebol are different, more Logo-like at the user level, but quite different even than that. For me, it's about what I can do best with each tool. Success is largely perception. Logo is Lisp (see Brian Harvey's works), and yet most people only think of it as turtle graphics for kids.
