Wow. 4 to 1, to Google. I am surprised.
I was purposefully not trying to work out whose results were whose, but there were little hints here and there.
I noticed on my first search that the results on the left (which turned out to be Bing) only had 8 results, as opposed to 10 on the other. I know there's been discussion on that elsewhere here though, on both sides changing the number of results. I wonder how much that affects the results.
