Earlier quoted context omitted.
The abuse of Occam's razor in this discussion warrants that level of sarcasm. And speaking of obscured points, what are you trying to say? Are you saying Facebook is _not_ working on an ad network that does cross domain tracking of users and displays ads based on social graph data, and this is simply a defensive patent? Or are you saying they are developing this feature, but we should trust your company to not abuse…
All I was trying to say was that there are reasons beyond desire to implement a product that would make a company file for a patent. I don't know anything about any product designed to do this, but I also don't know everything about every product at Facebook (it'd be impossible to get my own work done if that were the case).
Shame on me, but I don't follow Facebook's announcements about privacy enough - it never even occurred to me they'd deny something like thi Just like Google started out monetizing the semantic graph (and providing them an superior search engine in exchanges is their goal. I thought that was the whole point, and the reason behind the $80B valuation (ads served in a Google like way using the social graph instead of the semantic graph). It just follows that this would require a certain degree of integration between ad partners and user tracking.
ps -I'm not trying to single you out and lay the blame for all my gripes with Facebook on you, I hope it doesn't seem that way.
