This is such a neat concept. I would recommend anyone to check it out.
Pinterest is a Virtual Pinboard.
Pinterest lets you organize and share all 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. (from their website)
I love Pinterest. It is a cool way to organize information from the web. It also is a neat way to find cool sites that other people have found on the web.
