Social Bookmarking

From Wikipedia, the free encyclopedia

Social bookmarking is a web based service to share Internet bookmarks.

Social bookmarking sites are a popular way to store, classify, share and search links through the practice of folksonomy techniques on the Internet or Intranet.

Other than web page bookmarks, services specialized to a specific subject or format - feeds, books, videos, music, shopping items, map locations, wineries, etc. - can be found. Social bookmarking is also part of Social News Sites like Reddit.

History

The concept of shared online bookmarks dates back to April 1996 with the launch of itList.com. Within the next three years online bookmark services became competitive, with venture-backed companies like Backflip, Blink,[citation needed] Clip2, Hotlinks, Quiver, and others entering the market. Lacking viable models for making money, most of this early generation of social bookmarking companies failed as the dot-com bubble burst.

Social bookmarking inspired the social news movement which included sites like del.icio.us, reddit, Digg and the new Netscape portal.

del.icio.us

General description
A non-hierarchical keyword categorization system is used on del.icio.us where users can tag each of their bookmarks with a number of freely chosen keywords (cf. folksonomy). A combined view of everyone's bookmarks with a given tag is available; for instance, the URL "http://del.icio.us/tag/wiki" displays all of the most recent links tagged "wiki". Its collective nature makes it possible to view bookmarks added by similar-minded users.

del.icio.us has a "hotlist" on its home page and "popular" and "recent" pages, which help to surface interesting content and make the website an effective conveyor of popular internet memes and trends.

The website's simple HTML interface with human readable URLs, novel domain name, as well as a REST API and RSS feeds for web syndication, have contributed to making it one of the most popular services of its kind.

Use of del.icio.us is free. The source code of the site is not available, but a user's own data is freely downloadable through the API in an XML or JSON format, and can also be exported to a standard Netscape bookmarks format.

Everything posted to del.icio.us is publicly viewable by default, although a user can mark specific bookmarks as private, and imported bookmarks are private by default. The public aspect is emphasized; it is not focused on storing private ("not shared") bookmark collections. Many people use the del.icio.us linkrolls, tagrolls and network badges to display their links and information on their weblogs. Others use the RSS feeds and "daily blog posting" feature to do this.

There are a few open source clones of del.icio.us, such as de.lirio.us and sa.bros.us, as well as many competing Social bookmarking services, such as Simpy, BlinkList or Furl.

del.icio.us was acquired by Yahoo! on Friday, December 9, 2005. Various guesses suggest it was sold for somewhere between US$15 million and US$30 million.

The del.icio.us domain name is a popular example of a domain hack, an unconventional combination of letters to form a common word or phrase. del.icio.us, though not the first domain of this nature, is the best-known and most frequently accessed domain hack, and the Yahoo! acquisition is the highest-profile acquisition of a domain in this category. However, delicious.com also redirects to the del.icio.us website.
