Yeah...so on day 1, Bing goes after a bunch of exclusive indexing deals, and on day 2, Google does the same. Assuming you're a content provider who is willing to do a deal like this, and you're going to get roughly the same amount of money, who are you going to go with? Probably the guy who has 70% of the market. This seems like a quick way to get Google's market share to 80%.
