Pinterest is used to create bookmarks of websites, images and videos. The bookmarks are represented by screen shots, and are organized into themed boards that can be shared with others.
Pinterest is essentially a social-networking site, though the focus is on sharing links instead of on conversation. Users can create private boards with restricted access, or share collaborative boards with other users.
The site is free to use, but users must have a valid email address to set up an account. Links that are bookmarked are referred to as "pins." Users can upload their own images, which can become pins in their own right or may be used to represent a pin that links to something else. Boards are usually organized by a central theme or topic, such as family photos or favorite products. Businesses are also able to create their own pinboards. Similar to other social networks, a user can "follow" others users to get automatic updates from them.
Some websites have incorporated a "pin it" button that allows a user to automatically create a pin of the content on her board. A user must be logged into Pinterest to use this feature.
As of 2014, the companies Salesforce, Hootsuite, Spredfast, Percolate, Piqora, Curalate and Tailwind are given access to user data for marketing purposes.
