Pinterest is a virtual pin-board. Itís a photo-sharing social website that allows users to create and manage theme-based image collections such as events, interests, hobbies and more. Itís great for businesses having images or video associated with it, or those that can represent themselves visually. But, Pinterest is limited to some niches.
Just remember one thing clearly, pinterest is a community not a tool. So do not expect wonders out of it.
