Using Social Bookmarking

I am a new (and very enthusiastic) convert to social bookmarking. At first the concept seems simple: Keep your bookmarks online so that you can access them from any computer just by logging in. Then I really started to see the beauty of this system: Social bookmarks can be shared with others. I can see other websites that teachers like and they can see what I like. It's an easy way to filter through all of the information on the Internet and just weed out the really good sites. Now people have another easy and fast way to communicate across continents.
