>it will always lead to situations like that which are [bad]
I wonder if there isn't some definition analogous to "Turing complete" for social graphs? i.e. with a sufficiently powerful API, any question can be answered. Just as Turing complete-ness leads to viruses, worms, etc, might "XYZ complete" social networks lead directly and predictably towards A, B and C bad outcomes?

Perhaps. I'm not versed in them well enough to know. But I wonder if he isn't a bit Bill-Gates-eyan in his perspective of pushing the border between X-Y quite hard to see what bends and what breaks. For Microsoft, it was Code-Data and, while there were certainly people saying don't mix Code and Data!, people happily used their Excel spreadsheets and we suffered mightily from the resulting viruses. Whereas "viruses" were the unintended consequence of mixing Code-Data, are "outings" the result of mixing Social-Search?
