Definition: Pinterest

A photo-sharing site in the form of an online pinboard. Introduce in 2010, members post images ("pins") onto their boards for any purpose, including planning a wedding, saving recipes and redecorating a home. The Pinterest name was derived from "pin the things that interest you," and its tag line is "Organize and share the things you love."

Repin and Pin It
Members can "repin" images from other boards onto theirs, and all boards are identified by one of several categories, which are posted on the Pinterest menu. A "Pin It" button on the user's bookmark bar (the "pinmarklet") displays all the images on a Web page for ease of selection for pinning. Videos can also be uploaded to the site, which are featured in a separate section.
