The whole world should be using Scheme
A cool implementation to be sure (it has an amazing wealth of integration with Obj-C on the Mac which is my platform). But, holy god Common Lisp is messy! SLIME? Why? I just want the interpreter running in a buffer along side the file I am editing! No need for all of the crazy connection routines.
Scheme is slim, and so much more intuitive! QUACK + mzscheme is a breeze to get running in Emacs, loads quicker, and feels cleaner...
