To the defenders of Bing - would it be ok if Bing similarly used visits to amazon.com and various URL parameters to reimplement their "bestselling" lists for each category? I'm sure they could, and it seems clearly unethical. They are doing the same to google, right?
you still didn't get it, they are using clickstream from every possible source from amazon to ebay to google. and there is nothing unethical about it, as it just gives them annonymous data about which site people are clicking to. Google gets the same data from google toolbar and other products.
