Bing and Facebook New Search Feature

The Most popular Social Networking site "Facebook" and Micro$oft's Search engine "Bing" have teamed up, recently revealing new search features. Micro$oft is adding "input from users" feature, using Facebook data in the results of a search, giving an idea of what your facebook friends think on a particular topic. Both companies stress privacy is a priority, but the advertising opportunities will be tempting

Although I have not seen  this feature in action, It sounds to be much like the "Social Circle" feature in Google + Buzz
