Before clicking on the link, I expected failure. Turned out it is a success story, and I am a bit disappointed. I have seen "code cleanup" that made things worse countless times. Especially if the idea is to dedicate time just for that, instead of doing it as you go. I expected the article to be about one of these failures. The article describes 7 points, and suspiciously nothing goes wrong. It is rarely how it happens, there is typically some trial and error involved, and knowing what failed is as important if not more so than the final solution that works for you.
