Pinterest is a pinboard-style social photo sharing website that allows users to create and manage theme-based image collections such as events, interests, hobbies, and more. Users can browse other pinboards for inspiration, 're-pin' images to their own collections or 'like' photos. Pinterest's mission is to "connect everyone in the world through the 'things' they find interesting" via a global platform of inspiration and idea sharing.
