The Social Bookmarking Quick Start Guide

In a social bookmarking system, users store lists of Internet resources that they find useful. These lists are both accessible to the public or a specific network, and other people with similar interests can view the links by category, tags, or even randomly. Some allow for privacy on a per-bookmark basis. They also categorize their resources by the use of informally assigned, user defined keywords or tags. Most social bookmarking services allow users to search for bookmarks which are associated with given tags, and rank the resources by the number of users which have bookmarked them. Many social bookmarking services also have implemented algorithms to draw inferences from the tag keywords that are assigned to resources by examining the clustering of particular keywords, and the relation of keywords to one another.
