Early this week, Instagram announced that it has half a billion monthly active users. Of that 500 million (80% outside of the U.S.), 300 million log onto the app daily, sharing 95 million photos a day and tapping the “like” button 4 billion times daily.
These are massive numbers. But let’s put that into context. Twitter currently has 310 million monthly active users. Instagram gets to that number in about 30 hours. It’s interesting comparing Twitter and Instagram — Twitter has struggled to keep their user growth numbers from plateauing after initial buzz wore off, but in the past 2 years alone Instagram’s user base has doubled.
