Microsoft has already made its "decision" engine get all buddy-buddy with Facebook and Twitter, but now it's taking the integration one step further. You'll now actually be able to tag your friends in searches. Why, pray tell, would you need to do such a thing? Perhaps you've got a buddy who grew up in Paris and need suggestions for where to eat while you're visiting. Or maybe you've spotted an awesome hiking trail and want others to tag along. Just enter the question in the Bing side bar then tag the appropriate people. The search will show up on your timeline and others can pitch in. Of course, you could always just ask these same people via Facebook message, text or (gasp!) in person. But why would you want to simplify matters? Check out the source for more info and the video after the break.
