Pinterest is a vision board-styled social photo sharing website and app where users can create and manage theme-based image collections. Users of Pinterest curate themed image boards, populating them with media found online using the “Pin It” button, or uploaded from their computer. Each such item of media is known as a “pin,” and can be a picture, a video, a discussion or a monetary gift. Pins can be grouped into “boards,” which are sets of pins created on a given topic.
