I had pointed out to me in email that a question on Scotland Yard over at Ask Yahoo starts off by searching for the answer in Yahoo, only to give up and find the answer in Google. Why might that be?, the writer asked.
My answer is that it’s purely an issue of the date: Nov. 22, 2000. Yahoo wasn’t spidering as aggressively (at all?) back then, so it relied on Google for search results. While it would be a good story to find that Yahoo still relies on Google, this factoid doesn’t prove it.
