Hmmm ... I wonder if they are going to be sure to filter out adult stuff? LOL
I can see one of my sons searching for some kind of sexy picture (I know, teen boys would never search for THAT) and it saying "You Dad Likes...." (You get the idea)
Or maybe my wife looking for some new undergarment deals, and it saying "Your Husband Likes..." (again, you see where I'm going)
I know, I know... if I don't want people to know, maybe I shouldn't be doing it, right? Where was that opt-out of my stuff being shared again? Ah... Bing!
Seems like a good time for MSFT to punch out a commercial about social search... and show some wife following her mate into a sex shop. (For added effect, she can use an Android phone to track him, and Google Street view to learn where the shop is)
