My take on this is quite the opposite. If MS thinks they're doing nothing wrong, they shouldn't stop. They should do what is best for their customers.

Reversing what they do now because Google "caught" them, would IMO, imply they were doing something wrong and got caught.

I personally think what Bing is doing is great. I regularly use Bing and Google. I wish there were a streamlined way for me to broadcast to both of them... "for search term X this is the relevant link!"

MS has found a way to do this, and as long as its opt-in, I like it. I wish Google had the same (although I do realize that since Google owns so much of the traffic it is less of an issue for them -- its a net loss in terms of the flow of information).

But maybe a question for Matt... Can you and MS work together for a toolbar that does just this for both engines?

As a user this isn't a matter of Bing copying Google or not. But its about the fact that search relevance still kind of sucks. I feel like I can make the search experience better, especially in those occassions when I go to your competitors site.
