i did a search for someone recently and their facebook profile was the #7 result. after the typical "Firstname Lastname | Facebook" title link there was a list of 5 friends in grey font (#676767) in this format: Friends: Firstname Lastname, Firstname Lastname, Firstname Lastname, Firstname Lastname, Firstname Lastname i hadn't noticed this or seen it mentioned before.
i just checked again and the list of friends has changed since first looked, although if i refresh or try another browser it is doesn't change.
not every facebook listing in results returns the name list.
I see it too, and along with it comes a most awful feeling of being invaded and violated. This is at least as bad as the Buzz fiasco, IMO. Time to fix that Facebook privacy option that I've been delaying.
