Social bookmarking is a way for Internet users to store, organize, share and search bookmarks of web pages.
In a social bookmarking system, users save links to web pages that they want to remember and/or share.
This is different to using your own browser bookmarks and can be accessed from any computer the user wants.
You can use the links to share this article on the social bookmarking site of your choice.
