I really, really never understood why to indent with spaces, instead of tabs. I hoped this would've changed, but no... I want to set for myself how much spaces represent an indentation, not someone else, it depends so much on your setup, the monitor, resolution, font settings, editor setup, if 2 spaces are fine, or 3 or 4...
