Pinterest is a free website that requires registration to use. Users can upload, save, sort, and manage images—known as pins—and other media content (e.g., videos) through collections known as pinboards.
Pinterest is a social network that allows users to visually share, and discover new interests by posting (known as 'pinning' on Pinterest) images or videos to their own or others' boards (i.e. a collection of 'pins,' usually with a common theme) and browsing what other users have pinned.
