It is maddening that there is even still a "discussion" happening. Tabs for indentation, spaces for alignment. Didn't even get mentioned in the article. All the pros, zero cons. Enough of this. Enough, enough.

"Use tabs for indentation, spaces for alignment: the superior approach. Code is indented and aligned properly, and indentation is flexible. Use spaces for both indentation and alignment: still fine, but not flexible enough. Use tabs for both indentation and alignment: completely unacceptable, leads to headaches."

Since this also happens every time, if you're currently writing a harebrained reply about "mixing tabs and spaces!!!!", you don't understand what's being discussed and should permanently recuse yourself from the conversation.
