Del.icio.us

The website del.icio.us is a social bookmarking, social software web service for storing and sharing web bookmarks. The site came online in late 2003 and was developed by Joshua Schachter, co-maintainer of Memepool.

Everything posted to del.icio.us is publicly viewable by default, although a user can mark specific bookmarks as private, and mass-imported bookmarks are private by default. The public aspect is emphasized; it is not intended to be a tool for storing private bookmark collections. Many people use del.icio.us to publish "linkblogs" on their weblogs.

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 also makes it possible to view bookmarks added by similar-minded users.

The emphasis on recent additions makes it a convenient mechanism for propagating internet memes and trends.

Simple HTML interface with human readable URLs, as well as a REST API and RSS feeds for web syndication are used on del.icio.us.

Use of the service is currently free. The source code of the site is not available, but a user's own entered data is freely downloadable through the API.

The website has an unconventional domain name, known as a domain hack, which may have contributed to its popularity. It was the second Internet company hosted on a domain hack that Yahoo! acquired, blo.gs being the first.

The websites de.lirio.us, del.not.us and sa.bros.us are open source clones of del.icio.us. There are a number of innovations around social bookmarks beyond simple urls. Flickr bookmarks pictures, YouTube bookmarks videos, and Digg bookmarks news.

Yahoo! acquired del.icio.us on Friday, December 9, 2005.
