We use spaces here so that we can use -tabwidth=4 to get
code that is narrower on the page. This is important for the
Go by Example site because of the typographic / layout approach
it uses. If we used tabs that were 8 spaces it would be harder
to get code that satisfied our text column width requirements on
the page. So I don't think I'm going to change this for now.

Thanks for bringing it up though.

Cool, I was sure there was a good reason, just wanted to know which was it.
