What is bookmarking?
Bookmarking is a way to keep track of your favorite websites using...another website! Traditional favorites can be organized into folders (essentially assigning each link one category) while bookmarks are organized by tags (giving each link unlimited categories, which makes them easier to find later).
Why bookmark socially?
By keeping track of your favorites online, you can access them from any computer and easily share them with others. Tags and search functionality make your links easy to locate later. You can also keep them selectively private, allowing you to keep your professional and personal favorites all in one place. And the bookmarking community is a great place to find new and interesting resources on the web.
