Pinterest is a visual bookmark hosting silo where users "pin" (bookmark), or "repin" (repost a bookmark of) a page with a specific image from that page to a "pinboard" (named bookmark collection) and follow other users and/or pinboards created by others.
Displays a list of your pinboards with thumbnails of some pins on that board.
