I use Emacs. Specifically I currently use GNU/Emacs 23.1! The first version I used was 21.3 on a Slackware Linux.
I mainly use Emacs with Gnus, Org-mode and as an everyday editor for my daily needs.
I love the zenburn color theme and when possible (read: when X11 is available) use the Droid Sans Mono font.
I sometimes blog about emacs here.
