Earlier this week, Pinterest CEO Ben Silbermann announced that users contributed over 30 billion Pins since the service was founded.
This number increased by nearly 50% in the past 6 months. Pinterest users have created over 750 million boards in that time. Part of this growth was driven by Related Pins.
Over 90% of Pins have Related Pins connected to them and the number of people that repine Related Pins has grown by 20%. Silbermann compared Pinterest to curation in other forms like art being selected for museums, photos/articles in magazines, and clothing collections at retail locations.
