What is Social bookmarking? Please someone explain me... I am completely confused.

A social bookmarking service is a centralized online service which enables users to add, annotate, edit, and share bookmarks of web documents. Many online bookmark management services have launched since 1996; Delicious, founded in 2003, popularized the terms "social bookmarking" and "tagging".

Social bookmarking is designed to spread the word about a deservedly interesting internet source via social bookmarking sites like Delicious, Digg, and quite a few others. In SEO, social bookmarking has become a great tool in spreading your web presence using your target keywords as bookmark tags and allowing you to place your links. If you get to know which bookmarking sites offer do follow links, social bookmarking will increase your link value and as you know the link is the most important commodity in SEO. Don't disregard no-follow links from social bookmarking sites either as any "healthy" site has a natural combination of doing and no follow links.

It is tagging a website and saving it for later. Instead of saving them to your web browser, you are saving them to the web. And, because your bookmarks are online, you can easily share them with friends.

Social bookmarking is a method to submit website or an individual web pages in social bookmarking sites like:
Pintrest
Plurk
Diigo
Reddit
and many more.

Social bookmarking is the method of submitting your website in social network which will help you to attract more traffic to your site.
