Tabs, but this shouldn't be an issue for programmers using a real editor, something more sophisticated then Notepad. Vim can convert between tabs and spaces easily, and almost every modern editor I've used can do the same. Using spaces to force everyone to your preferred indentation is like forcing the font size. I can't read code indented two spaces, but if we use tabs I can set the indent to 4 spaces widths and someone with younger eyes can use 2.
