The reason the tabs vs spaces debate is silly

is because spaces are vastly superior. And I'm not sure how so many people were convinced otherwise. The biggest issue with using tabs is that people tend to want different tab widths for code versus other scenarios, like tab delimited data files for example. I would want 4 for the former and 8 for the latter. Changing it based on file type still leaves you with some bad scenarios.

And the reasons idiots use tabs are horrible.
-Tabs create smaller file sizes. Do you also use smaller variable names? This one is nonsense.
-Tabs allow you to control the indentation on your end. You don't get to decide what the code looks like that someone else wrote. I cringe when I see an opening brace on a separate line, but there's nothing you can do about it.

Also, if you're using an editor that shows whitespace, spaces look way better than tabs. Please stop using tabs.

One space is clearly the superior choice. You get code that looks the same everywhere, saves on filesize, and you don't have to use the awkward tab key. As an added bonus, the column counter tells you exactly what indent level you're on.
