I'm vaguely disturbed by all the talk about "sites people want to see fall". That sounds like almost manual bias against certain sites to me. Didn't hear anything about language analysis and figuring out what is high quality vs low quality content.
The official Google post on this update addresses that. This change is purely academic, not based off feedback data from their recently launched spam tool.
I didn't say that it was based off of the spam tool. But going on Google clearly had targets. It's not like they couldn't figure out what farmers were without the tool.
