The textual content of this article is spot on. However i do have to wonder why they chose to show a photo with code that indents 11 levels deep at the top of an article about code quality.<p>I know it's hard to teach programmers how to avoid situations like that, and how to avoid or reduce duplication, because i struggle with this with most of my colleagues. However in a company where code is the bread and butter of everything the company does, i'd expect things like that to be addressed before tabs-vs-spaces.
