Bing sees things differently

I saw this 8 hours ago via this link: http://news.ycombinator.com/item?id=635819

It took me ages to see what the point was, but when I did I was unsurprised. Perhaps that's a comment on my expectations and world-view, rather than on the actual content.

I wonder how they get these different results. Do they deliberately massage the results? Do they hand pick the searching? Or is it something else.

Answers on a postcard ... (now there's a web-app waiting to happen)
