Tabs versus spaces
(Source for this image)
I'm in the "spaces" camp myself. I used to work in a shop with a bunch of Windows programmers who used tabs (that's what their IDE did). In an effort to try to fit in, I configured my .emacs file to use tabs. Still, my preferences are for spaces.
Of course, the most cogent article I've read on this topic comes from jwz.
