Social bookmarking is a way to keep track of websites--like using "Favorites" or "Bookmarks" in your browser--using a free online account that you can also share with your friends.

Because your favorite websites are organized online, you can find them anytime, no matter what computer you're on.  This is really great if you sometimes work from home, travel, or use public or shared computers.  There are two more really good reasons to use a social bookmarking system.  First, it can be social--you and your friends (or colleagues, peers, teammates) can share lists of websites.  This way, if a friend finds a good site and bookmarks it, you'll know about it too.  Secondly, like many other Web 2.0 applications, social bookmarking services allow you to use tags (descriptive keywords) to label your content.  When you tag your favorite websites, you create an index that allows you to find exactly what you want later on, without needing to remember the names or URLs of the websites.

There are many different social bookmarking services out there.  Here's a link to an article (published Oct. 2008) on the top 30 social bookmarking services:  http://www.ebizmba.com/articles/social30.
