Mark Zuckerberg came away with a win yesterday in his marathon five-hour appearance before Congress; Facebook shares closed the day up 4.5 percent, its best trading day in two years. Wearing a navy blue suit and a royal blue tie instead of his usual T-shirt and jeans, the Facebook CEO sounded smart answering questions about how Facebook’s services work. He fielded a couple of tough questions: Sen. Lindsey Graham essentially asked if the company was a monopoly; Sen. Richard Blumenthal asked if the company would agree to having users consciously opt in to let companies use their data, instead of the current opt out by default. At the end of the day, many of the senators said that they looked forward to working with Zuckerberg on whatever regulation comes about. He’ll be back today at 10 am ET for a separate hearing in front of the House Commerce Committee. [Kurt Wagner / Recode]

Don’t give away historic details about yourself on those seemingly innocuous quizzes, games and surveys on social media sites.
