Social bookmarking is a method for Internet users to organize, store, manage and search for bookmarks of resources online. Unlike file sharing the resources themselves aren't shared, merely bookmarks that reference them.

Social Bookmarking refers to web based applications that enable us to store bookmarks online instead of in our favourites or bookmarks on our computers. The immediate advantage of this is that we can access our bookmarked sites from any computer - even a mobile phone.

However bookmarks also have a distinct advantage over search engine results. Searching the internet with a search engine, no matter how good, means that the information is selected by computer software that attempts to determine meaning.

A list of bookmarks is the result of human action, we filter the sites we view and list links only to those sites that provide value. So if you share some of my interests you will problaly find it of value to access my bookmarks list rather than using a search engine. Social bookmark sites enable you make any link public or private so that we can make a selection of our bookmarks available to each other.
