Instagram’s incredible growth means that the service has now overtaken Twitter, with 300 million monthly active users compared to Twitter’s 284 million. That’s up a staggering 100 million in just nine months. “Over the past four years, what began as two friends with a dream has grown into a global community,” said Instagram CEO Kevin Systrom.

Many feared that Facebook’s acquisition of Instagram (for a cool $1 billion) would ruin the photo sharing app, but it actually continued to grow in popularity. There are now 70 million photos shared every single day, adding up to a total of 30 billion across the network.
