Using tabs over spaces is a catastrophic misunderstanding of modern text editors. Spaces are the ONLY one-size-fits-all solution for a multi-developer environment. Text editors can be configured to SHOW a tab character visually as any number of spaces you want - without changing the code. If someone likes 3 spaces, they can see a tab character as 3 spaces; if someone else likes 8 spaces, they can show each tab as 8 spaces. Treating a tab as a "tab stop" is the mindset of a typewriter user.
