Delicious
Hey, On June 1, 2017, Delicious was acquired by Pinboard, and the service will be discontinued in favor of Pinboard's paid subscription-based service.

Delicious (stylized del.icio.us) is a social bookmarking web service for storing, sharing, and discovering web bookmarks. The site was founded by Joshua Schachter and Peter Gadjokov in 2003 and acquired by Yahoo in 2005. By the end of 2008, the service claimed more than 5.3 million users and 180 million unique bookmarked URLs. Yahoo sold Delicious to AVOS Systems in April 2011, and the site relaunched in a «back to beta» state on September 27 that year. In May 2014, AVOS sold the site to Science Inc. In January 2016 Delicious Media, a new alliance, reported it had assumed control of the service.

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 was available; for instance, the URL delicious.com/tag/wiki displayed all of the most recent links tagged «wiki». Its collective nature made 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.

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 or JSON 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. Delicious linkrolls, tagrolls, network badges, RSS feeds, and the site's daily blog posting feature can be used to display bookmarks on weblogs.
