Today Bing has launched a host of changes that make intelligent use of the vast amount of data to use. These changes seperate the results in three categories which Microsoft mentions as “Search knows”, “Bing knows” and “Friends know”. Check this video by the Bing team out.
You can see a detailed hands-on by The Verge here. The new search looks amazing and I expect it to work very well too. This result will roll out gradually over the next month, but you can request an early access here. For users outside U.S. I would recommend that while using bing.com, they change the country to United States at this link.
