Facebook-owned Instagram today announced a major milestone as the service just passed 500 million monthly users, more than 80 percent of whom are living outside of the United States. The announcement came a little more than a month following Instagram's major redesign of its mobile app. The only metric that matters is daily active users and Instagram said that out of the 500+ million monthly users, 300 million use the service every single day.
