After all, friends suggestions and their expertise do matter :)
Bing will track recommendations from your peers on Facebook and will return granular, more relevant and specific search results to your interests.
Your search would be more like taking your friends along with and telling them about the laptop you are planning to buy; and they will guide you through what they "like".
This could be a major breakthrough in internet search. Further, it might give substantial edge to bing over its search rival Google, which might be working to exploit social search using data from orkut, but it has less user base than Facebook does.
To enable bing social search with Facebook; go to bing and follow below steps.
