You can download Pinterest app for iPad from iTunes and start pinning right from your iPad. If you don't know what Pinterest is, well it is a Virtual Pinboard. It lets you organize and share all the beautiful things you find in your life.
Pinterest allows you to organize images -- maybe latest gadgets or wines you've tasted -- into boards for specific categories. When you "pin" something new, your followers will see it. They can like, comment or re-pin it to their boards. You can read more about Pinterest and how to use it here.

• Repin, like and comment on your favorite pins.
• Follow and Unfollow users
