It'll be very interesting to see what this does to Bing's marketshare in six months or so, since Yahoo's search runs through Bing.
Although we might never find out, I'm very curious to find out the terms of the deal. Did Yahoo pay more? What about Microsoft? Were MS as motivated since they, essentially had two horses in the race (Bing and Yahoo) vs. Google? Lots of fun little details.
