Elliot Schrage, who oversees Facebook’s global communications and public policy strategy, said it was a good thing that young people are thinking about what they put online. “We are not forcing anyone to use it,” he said of Facebook. But at the same time, companies like Facebook have a financial incentive to get friends to share as much as possible. That’s because the more personal the information that Facebook collects, the more valuable the site is to advertisers, who can mine it to serve up more targeted ads.
