According to Pinterest "Pinterest is a Virtual Pinboard. Pinterest lets you organize and share all of the beautiful things you find on the web. People use pinboards to plan their weddings, decorate their homes, and organize their favorite recipes. Best of all, you can browse pinboards created by other people. Browsing pinboards is a fun way to discover new things and get inspiration from people who share your interests."
"A pin is an image added to Pinterest. A pin can be added from a website using the Pin It button, or you can upload images from your computer. Each pin added using the Pin It button links back to the site it came from."
HOW IN THE HECK DO I GET STARTED, WHAT IS PINTEREST FOR, AND WHAT IS EXPECTED OF ME?
