Google rolls out Social Search globally

For example, I will probably see my friend's opinion in a social search result. I might actually not like what he said or suggested, which he does not know that I don't like it. However, I do know I can ask him about the subject to find out his experiences or maybe get his second opinion.
That becomes powerful because it might cut the time for you to find the information you want. It's also more likely to save us from getting nowhere to find things we want.
So, relationships do help us find things quickly. And for those friends who give me wrong opinions will definitely lose my trust.
I know there are a lot of fake accounts on Facebook in our current FarmVille era (many actually named "Farm Ville") so that people can maintain a separate identity to play games. Is it going to come to this? That we're going to have to join interest groups or even create a new identity to make our searches not be full of worthless stuff?
I don't really look at likes data as improving the quality of my search. I think of it as asking my social graph what their opinion is. I expect that to tell me what's popular, not what's best.
I still wonder how I can inform a social search that I'm "me at work" -- i.e. I'm more interested in what's popular with Hacker News users, not the people I jibber-jabber with on Facebook. I'm constantly searching YC comments for any technical subject.
