Del.icio.u

Tags:

A social book marking site that acts as being a favorite’s manager for customers, much like an accumulation of favorite links. You can include your del.icio.us record and bookmarks, classify the favorites, label them as well as reveal them with others.
 

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 http://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.
