The data is simply too dirty to be useful for anything other than novelty searches, and possibly searches involving the 1%(?) of people that actually put their life graph on FB.

Maybe next step is FB adds user web surfing data (aggregated?, permission-based?) but hard to see how FB could pull that off?

I guess they are counting on the premise that in future people who have their info public on facebook will increase... Given the things they have accomplished so far and the amount of investment that has gone into facebook, It will not be surprising if someday FB does add user web surfing data... (permission-based of course)
