If you're still trying to figure out this trendy new thing called social bookmarking, you aren't alone. I've heard more than one person ask why they would want to use a social bookmarking site when they could simply bookmark web pages within their own web browser. There are several answers to this question, only one of which is "saving and organizing the pages you like best."

The team over at Common Craft have put together an excellent little video tutorial that explains exactly what social bookmarking is, why you might want to use it and how the social side of things adds even more value to these services.

Their example is focused on del.icio.us, but the same concept applies to all social bookmarking services. Give it a try at Furl or Magnolia too.
