That's a good question, actually. The answer is: Yes and no. Scheme, Emacs Lisp, Common Lisp and Clojure are all different, certainly. For example, when you look at programming texts, you realize that there really is a "Scheme" way of doing things and a "Common Lisp" way of doing things, which aren't always the same. That being said, if you learn one dialect, that will probably make learning another much easier. If you're new to the Lisp thing, I'd learn Scheme.
