Facebook announced on Tuesday that it now has over 2 billion monthly active users. "As of this morning, the Facebook community is now officially two billion people," founder and chief executive Mark Zuckerberg posted.<br /> “Each day, more than 175 million people share a Love reaction, and on average, over 800 million people like something on Facebook,” product manager Guillermo Spiller said in a press release. Last week, Facebook changed its "mission" from "Make the world more open and connected" to "Bring the world closer together", a move that reflects its growing emphasis on building online communities.
