This update seems to be directed at web sites running AdSense in general, as Google's definition of a "content farm" seems to be "a) a site with AdSense; b) any other variable", however odd this might sound.
I am not sure about that. Demand Media is loved by Google as it brings them in many millions of revenue every year.
You don't see that awful eHow being hit in the latest algo shift, which I liken to a blunt instrument battering by the front line.
There's a growing team of snipers in the background to pick off Google's competitors, especially in vertical search markets.
