This is an interesting move by Google but not completely off the rocker for them. Last year they clogged results for the co.cc domain because they considered they impure results.
Google plans to target far too improved websites because they want to level the stage for other websites who do not focus on such initiatives. Generally there are websites out there that really focus their initiatives on SEO and not content and those results would achieve greater rankings than websites that don’t focus on SEO.
