Tags are keywords people use to describe their bookmarks



What is a tag?
A tag is simply a word you can use to describe a bookmark. Unlike folders, you make up tags when you need them and you can use as many as you like. The result is a better way to organize your bookmarks and a great way to discover interesting things on the Web.

Tags are also called //tagging, blog tagging, folksonomies// (short for folks and taxonomy), or // social bookmarking .// 

On a website in which many users tag many items, this collection of tags becomes a folksonom y.

** Social bookmarking ** is a method for Internet users to store, organize, search, and manage bookmarks of web pages on the Internet with the help of metadata, typically in the form of tags that collectively and/or collaboratively become a folksonomy. Folksonomy is also called //social tagging//, "the process by which many users add metadata in the form of keywords to shared content".

In a social bookmarking system, users 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.

Most social bookmark services encourage users to organize their bookmarks with informal tags instead of the traditional browser-based system of folders, although some services feature categories/folders or a combination of folders and tags. They also enable viewing bookmarks associated with a chosen tag, and include information about the number of users who have bookmarked them. Some social bookmarking services also draw inferences from the relationship of tags to create clusters of tags or bookmarks. (tag clouds).

Many social bookmarking services provide web feeds for their lists of bookmarks, including lists organized by tags. This allows subscribers to become aware of new bookmarks as they are saved, shared, and tagged by other users.

As these services have matured and grown more popular, they have added extra features such as ratings and comments on bookmarks, the ability to import and export bookmarks from browsers, emailing of bookmarks, web annotation, and groups or other social network features. Founded in 2003, del.icio.us (now called Delicious) pioneered tagging and coined the term //social bookmarking.// media type="youtube" key="x66lV7GOcNU" height="344" width="425" [|**Social Bookmarking** in Plain English]    ·  All done by human beings who understand content.
