Tonight at an event in the company’s San Francisco headquarters, Pinterest CEO Ben Silbermann announced that users had contributed more than 30 billion Pins since the service was founded, a number that has grown by nearly 50 percent in the past six months alone. Users have also created more than 750 million boards in that time. (Update: Our initial story said 30 million, not 30 billion. Big difference.)
That growth has stemmed, in part, from the introduction of Related Pins, something the company released about a year ago. Nowadays more than 90 percent of Pins have Related Pins connected to them, and the number of people who repin Related Pins has grown by 20 percent.
