w00t!
I predict vim will win the poll (EDIT: whoops, I thought it was just vim and emacs.), it seems to be more popular.
I used to use it all the time (with a bit of gedit and KDevelop.), but then I took the time to learn Emacs and I love it. I still use vim just to change stuff really fast when I'm in a terminal in X (because Emacs would bring up the GUI. I could get around that by running "DISPLAY= emacs" (is there another/better way?), but I don't have a problem with using vim.), that's it.
Oh, I don't use emacs anymore. It's a fine text editor if you keep using it. I used it while I was learning it, and loved it, but now I could hardly make my way around it. Heh. I don't use text-based editors much at all, and vim works just as well and is easy to learn, and remember (the basic functionality anyhow).
I do my programming in the KDE
kate, and I really, really love it. I'm finally getting to appreciate it's split-window functionality, and it's all just goddamn brilliant.
screenshotIt's kinda like emacs, but I can sing praises for it without having the manual open..
