2 Spaces or 1 Tab, what's the standard for indentation in the Rails Community?
As for all the arguments about different editors showing tabs with different widths...
It is a configuration setting people!
Change your editors to use two spaces for each tab. Different widths in different editors is not an argument. It is a moot point. If anything, using tabs allows people who prefer different widths to set and use the width they prefer. Hell, I think I like 3 spaces.
And you have to hit backspace twice just to un-indent something once. I'm a programmer, I'm lazy. I don't like to do things more than once!
