For those of you keeping score at home, Instagram just passed the 80 million-user mark. The milestone comes less than three months after the Facebook-owned mobile app surpassed 50 million users.
“This means the app has managed to increase its user base by more than 10 million users on average per month,” CNet points out. “Make no mistake: The timing of the announcement today
isn't accidental; Facebook, which announced in April that it is acquiring Instagram, is today releasing its first earnings report as a public company.” Instagram also revealed that its users
have shared almost 4 billion photos.
