Article about Delicious.com

Delicious is a social bookmarking web service for storing, sharing, and discovering web bookmarks.Delicious uses a non-hierarchical classification system in which users can tag each of their bookmarks with freely chosen index terms (generating a kind of folksonomy). A combined view of everyone's bookmarks with a given tag is available; for instance, the URL http://delicious.com/tag/wikidisplays all of the most recent links tagged "wiki". Its collective nature makes it possible to view bookmarks added by other users.

Delicious also allowed users to group links with similar topics together to form a "Stack", and include title and descriptions for the Stack page.Stacks could be worked on collaboratively with other users, and could be followed and shared with other users. Stacks were added in September 2011 and removed in July 2012.

Delicious has a "hotlist" on its home page and "recent" pages, which help to make the website a conveyor of Internet memes and trends. Users can also explore stacks on the home page by navigating categories like Arts & Design, Education, et cetera.

To facilitate newcomers, Delicious provides an option to import bookmarks from the web browsers to its site so that new users can quickly get started with the site.

Delicious is one of the most popular social bookmarking services. Many features have contributed to this, including the website's simple interface,human-readable URL scheme, a novel domain name, a simple REST-like API, and RSS feeds for web syndication.

Use of Delicious is free. The source code of the site is not available, but a user can download his or her own data through the site's API in an XML orJSON format, or export it to a standard Netscape bookmarks format.

All bookmarks posted to Delicious are publicly viewable by default, although users can mark specific bookmarks as private, and imported bookmarks are private by default. The public aspect is emphasized; the site is not focused on storing private ("not shared") bookmark collections.^[7] Delicious linkrolls, tagrolls, network badges, RSS feeds, and the site's daily blog posting feature can be used to display bookmarks on weblogs.

There are several competing social bookmarking websites including some open source clones.
