The primary use of social bookmarking sites is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too.

• You can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.

• You can also see the interesting links that your friends and other people bookmark, and share links with them in return.

• You can even browse and search to discover the cool and useful bookmarks that everyone else has saved -- which is made easy with tags.

While this opens up more sources of information for you, be aware that tags are often inconsistent, confusing or corrupted by website owners spamming social bookmarking sites.
