Web 2.0 Question:

Social Bookmarking allows users to share their user-generated internet favourites or bookmarks. Traditionally users would have a list of favourite websites as part of their own internet browser. Now, social bookmarking allows these lists to be shared easily so that anyone can use them. The content can be classified using tags to make them easier to search and use. http://del.icio.us (owned by Yahoo) is a good example of social bookmarking and shows users how many other people have saved a particular site.
