Sheryl Sandberg, COO of Facebook, live at D11

Sheryl Sandberg has served as the chief operating officer of the world's most popular social network since 2008, and today she's taking the stage at D11 here in Rancho Palos Verdes, California. She's kicking off a day of high-profile interviews just hours after Apple CEO Tim Cook got things started last night, and we're expecting her to be grilled on all manners of things -- the company's stock price, the future of mobile advertising, the success (or failure) of Facebook Home, international growth and how many Likes this here liveblog will receive. Join us after the break for the blow-by-blow, won't you?
