Here's a NYTimes article on retargeting: http://www.nytimes.com/2010/08/30/technology/30adstalk.html http://www.nytimes.com/2010/08/30/technology/30adstalk.html Many people think this is creepy and privacy invasive. For example, in the past I've had a hard time explaining why an ad for silencers keeps following me around. I do wonder at the tradeoff between retargeting people and getting that triple exposure for your product versus the creep factor that people have when they see you doing that.
