Doing a search will have the top results being pages that friends, or friends of friends have linked to, or retweeted. In the results window you'll see what they said about it. You'll then have the opportunity to contact those people (if they've got that setting on) - and in time, you'll get new friend recommendations based on what you're searching and clicking: so social search leads to search-based matchmaking. It could also lead to interest groups, especially location-based interest groups from a bunch of people in similar social circles, thereby leading to meetups. You could also put out requests for help, and those requests for help will be distributed to the right friends (by way of what they've been searching for lately), so they can respond. FB can feed their timelines into Bing (or their own search engine) so Bing can go grab content in realtime as it's linked, rather than take the shotgun approach spidering. And then FB would harness that system. So basically social search gives a better picture on an individual's interests, and how recent, or how long that interest has been to a person. This where Google really needs to catchup: they should really see themselves as a tiny startup against massive FB. They should see their users as individuals amongst a group of friends, rather than as silos with intentions. They should hire FB engineers, look to their own ranks for FB power users, maybe even find some people who Zuckerberg has pissed off to help.
