Social Bookmarking

Social Bookmarking is a method for Internet users to share, organize, search, and manage bookmarks of web resources.
In a social bookmarking system, we can save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine.
In the process of teaching Social Bookmarking can be useful as a way to access a consolidated set of bookmarks from various computers, organize large numbers of bookmarks, and share bookmarks with contacts, so this allow students to check some activities that can be useful for them, to reinforce the knowledge.
