Knowledge still rules. If you know what you are doing it is possible to churn out low quality sites which exploit weaknesses in the Google algorithm. You just need to hope you are smart enough to make enough money before Google closes the exploit and you need to seek out another weak spot.
Google's algorithm will always have some flaws. That doesn't mean its a bad algorithm. When I find unusual serps I like to take the time and reverse engineer it. It helps me to learn new techniques which sometimes can benefit my mainstream sites and other times helps me to discover new spam areas to avoid getting accidentally flagged with.
