Pin It On Pinterest places a "Pin It" button at the end of your posts, and allows you to predetermine what gets "Pinned" at Pinterest. Spawned by the idea of Jamie Swanson of The Modern Tog and developed by William Bay of Flaunt Your Site.

Pinterest is one of 2011's fastest growing websites, with the potential for substantial amounts of traffic from users reviewing the Pins that users have posted.

Simply install it, and you will find a new form underneath your Post Editor where you can fill in:

1. Description.
2. An image to associate the post with.

When you've added both the description and image, you can publish your post, and you will have a new Pin This button under your blog post. It will also show the number of times people have pinned your blog.
