I'm shocked at the amount of suppport on HN (thus far) for Bing's attitude on this issue. I understand that they may well not target Google's SERPs specifically in their clickstream analysis but they should certainly have excluded Google from it, for ethical reasons. Google state that Bing created associations from clickstreams through Google's SERPs on common queries (e.g. the tarsorrhaphy spell check test), not just long tail queries. Given that Google is extremely popular, this must have given a lot of weight to clickstream signals resulting from Google SERPs on many occasions, for common queries. That is entirely unethical and I'm shocked so many here don't find a problem with this. Take the case of a highly-ranked great result on Google for a particular term, which Bing rates lower due to inferior algorithms. Bing's analysis of Google users would send that result higher in the Bing SERPs, mainly due to Google's expertise in highlighting that site, and only to a small degree due to the user's choice of clicking on it. That to be does fall under "copying" Google's results, it may not be illegal, or intentional, but copying it remains. Bing should have excluded Google from their clickstreams, and I certainly hope Google exclude Bing from their's. (Matt Cutts stated they do in the video.)
