GregAWoods uses Emacs.
Once upon a time was the PCL-CVS maintainer.
Has used many different major and minor variants of Emacs and Emacs-like editors, but never XEmacs for some odd reason.
Most favourite ErsatzEmacs implementation is Jove. It is by far the most stable and bug-free of all small/micro Emacs implementations, though it has serious limitations.
