Basically, gone are the days where you can just patch together a quick website with some defacto content and expect it to rank.
You have to take all things into consideration when releasing a new website.
Johnmu just posted on his twitter about making sure your contact forms work properly, I think this is very important as well...make sure your website works. I think a broken website in googles eyes is a big time indicator of poor quality. I think this update was more about the quality of the website itself rather than the actual content.
