I'm also an Emacs guy, but I agree with the post's assessment of the complexity of starting out with Emacs vs. another editor.

I prefer Emacs because it is so easy to switch between buffers holding different files, or different places in the same file, because it has keyboard macros, its infinite customizability, Org-Mode, etc., etc.

But that's a lot to learn, and if you are trying to learn Clojure, you should use whatever allows you to focus on the language itself.

You gotta tell us why man. Don't leave us hangin'.
