The website del.icio.us (pronounced as "delicious") is a social bookmarking web service for storing, sharing, and discovering web bookmarks.
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 . A combined view of everyone's bookmarks with a given tag is available; for instance, the URL "http://del.icio.us/tag/sravan" displays all of the most recent links tagged "sravan". 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.
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, , 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.
The del.icio.us domain name is a popular example of a domain hack (delicious), 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. However, delicious.com also redirects to the del.icio.us website.
