The news title finally mentioned "brokers."Much have been talked about the ease of collecting and extracting data, I'm wondering when it comes to SELL data, how easy would that be and through what process a developer could find a broker? And at what price? Is there a way to find a list of these brokers?

Would it be difficult for facebook to be aware all data brokers in the market and also at what price point, under what agreement and and estimated transactions volume?
