Bing has announced it will allow users to bias search results, based on what their ‘friends’ of Facebook are searching for…
“Bing will incorporate users’ social data from Facebook to improve the personal relevance of your search results starting today. Facebook founder Mark Zuckerberg, Bing leader Qi Lu, and longtime Microsoft online veteran Yusuf Mehdi announced the news at Microsoft’s Mountain View office this afternoon.”
It’ll be interesting to do a test when the service rolls out, to find out if it actually improves the results or not. I suspect not, since most people are i) bad at searching, and ii) not using Bing.
