Delicious is a social bookmarking website. The primary use of Delicious is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too. On Delicious, you can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.

You can also use delicious to see the interesting links that your friends and other people bookmark, and share links with them in return. You can even browse and search Delicious to discover the cool and useful bookmarks that everyone else has saved -- which is made easy with tags.

Delicious was acquired by Yahoo on December 9, 2005. No formal acquisition price was disclosed, though it has been speculated at $10 to $15 million. Early seed round investors include Marc Andreessen, Tim O'Reilly, Esther Dyson, Josh Kopelman, Bob Young, Seth Goldstein and Howard Morgan.
