The fact that Google is attempting to define and thus strongly normalise what is human behaviour is definitely a big red flag to me. ...But this is their core search competency and exactly what makes their search so powerful. Page rank is basically distributed wisdom of crowds, aka algorithm of how people behave (build their websites) based on a search term/imbedded link. This seems like a perfect extension of this.…
Their search is only "powerful" for finding the more mundane and widely disseminated information; I've noticed that it's increasingly difficult to find very specific information with it as it basically misunderstands the query and returns completely useless results. Maybe that's why I look like a bot, as I try to tell it exactly what I want...
Google seems robust because humans generally think pretty similarly, and generally look for the things that the people around them are talking about or also looking for. That breaks down considerably though across cultures and time.
