Mr. Gupta, I'd like to get a sense here about the collection and marketing of personal information by social media providers. Is it part of a business model? Can they survive without that, with only the advertising that they have on their sites? It seems, and we've heard that as testimony from a witness, that part of the game is collecting data on people and then marketing it so they can derive a revenue stream and, through that, they could be compromising the privacy of individuals. What I'm asking is, the business model to make this profitable, does it rely on that personal information to the extent that they couldn't afford not to have it?
