A , rolling out to all users now, suggests Facebook friends who might know about a given topic, and shows activity from high-profile people on other social networks such as Twitter. The social search results are a direct shot at , but they aim to be less intrusive by staying out of core search results.

I've been poking around with the new Bing, and I think Microsoft succeeded in adding social search results that don't get on your nerves. Still, Bing has lots of room to improve in the actual results that it serves up.

The new Bing lets users ask questions of their Facebook friends from within any search results page, so if you're looking for a place to eat or something to do, you can get advice from friends alongside whatever the search engine spits out.

Of course, posting to Facebook from Bing requires you to grant permission from within Facebook. By default, only friends will see your questions from Bing, but you can change this option from the permissions page or from within Facebook's privacy settings. You'll also see an additional permissions page the first time you post, just to clarify that anything you post in Bing will show up in your Facebook Timeline.
