Facebook Swears It’s Cool Among Teens — Really

The trouble is that the company’s attempts to quiet the story just draw more attention to it. The latest attempt came on Friday when Facebook chief operating officer Sheryl Sandberg said that Facebook’s challenges with some teens have been “blown out of proportion” and that “teen usage of Facebook remains stable.”

Facebook’s popularity with teens is important because young adult buyers are especially coveted by advertisers, and there’s a worry among some investors that if younger teenagers stop using the service in high school, they’ll use it less frequently in college, too.
