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/wiki displays all of the most recent links tagged "wiki". Its collective nature makes it possible to view bookmarks added by other users.

 

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.  Use of Delicious is free.

 

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.
