How does Pinterest work?
The site is designed for its members to organize images, much like scrapbooks or photo albums, by posting personal photography and images found online of favorite items, creative inspirations and wish-lists, for example. The images are posted into idea boards created by users for specific categories.
When a user "pins" an image, their followers see it in a similar way to Facebook streams. Followers and browsers of the Pinterest website may then "like" and "comment," or "re-pin" it to their own boards. In very much the same manner as other social media content is broadcast, Pinterest pins can go viral, with additional exposure feeds going to Facebook and Twitter.
Like both of those sites, the strength in Pinterest's potential lies in the numbers: how many new and existing clients can be reached. An optimal tactic to garner attention is to "follow" fellow members.
