Blogs, wikis, and other nifty Web-based tools, ones that enable everyone to create and distribute content like never before, get all the glory, it seems. Then there are the applications that help them organize all that material that they consume online. Though not as sexy, perhaps, as blogging or podcasting, social bookmarking is equally empowering to users, helping them make sense of what they find and use on the Web and, even better, enabling them to share their treasures with others. While traditional library methods have effectively tamed print resources, the digital content residing on more than one billion Web pages is a different beast altogether. Enter social bookmarking, tagging, and folksonomies. In a nutshell, the operating principle behind these concepts is this: if one finds something interesting enough to save, odds are good that you will, too. And together, using these tools, everybody can build comprehensive resource lists much more effectively than any one of them could working alone. Exemplifying the wisdom of crowds, these applications are fast becoming an important resource for relevant information.
