The correct title of this article is del.icio.us. The initial letter is shown capitalized due to technical restrictions.

The website del.icio.us (pronounced as "delicious") is a social bookmarking web service for storing, sharing, and discovering web bookmarks. The site came online in late 2003 and was founded by Joshua Schachter, co-maintainer of Memepool. It is now part of Yahoo!.

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 competing Social bookmarking services, such as Simpy, BlinkList or Furl.

del.icio.us was acquired by Yahoo! on Friday, December 9, 2005.[1] Various guesses suggest it was sold for somewhere between US$15 million and US$30 million.[2][3]

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.
