Gosh is there going to be anything that google hasnt got its finger in the pie?
by serving DNS: it would now know everywhere you were going, regardless of whether you went through Google Search or whether the site had Google Analytics installed.
Its actually beginning to be a bit scary about how much google are taking over.
It makes me laugh that Alexa is classed as spyware by the likes of so many spyware detectors... yet google is already far more intrusive and knows more about us already than Alexa does. Could just see the reaction if the likes of S+D etc etc attempted to class google in the same way it does with alexa.
