What is Social Bookmarking?

When you save a web page link by adding it to your browser’s 'Bookmarks' or 'Favourites', you can only access it again on the computer you saved it on. Social bookmarking tools like Delicious, StumbleUpon and Facebook enable you to save and share web page links on the Internet.
By saving your favourite pages this way, you can:
Access your bookmarked links from any computer
Organise your links by attaching your own keywords or 'tags' to them. You can also find new sites that people have tagged with the same keywords you used.
Send links to friends and share them with other people with similar interests - hence the name
‘social bookmarking’
To begin bookmarking, you can either sign up to a specific service like Delicious or StumbleUpon, or you can do it through a site that provides various online services, like Facebook. These sites are usually free to use, but you need to register with them first.
