Pinterest allows you to visually "bookmark" all those great articles, ideas and thoughts you find out on the Internet. Users create pinboards that help them organize their collection for ease of searching and sharing. You do have to receive an invitation to join Pinterest.
Once you start using Pinterest, you can create you own boards, follow other people's boards and even collaborate on a board with other Pinterest users. Educators have started using this new to collect bulletin board ideas, classroom decor and organization, lesson plans, virtual field trips and more.
There have been some copyright issues recently connected with Pinterest, so make sure you read this blog post - Do You Have Permission to Pin? - before you start pinning and sharing.
Here are some additional resources to get you started and give ideas on how educators are and should be using Pinterest:

*I have been told that Pinterest is a "girly" site. There is a more masculine site that works similar to Pinterest called ScoopIt! You do not need to be invited to join this site.
