What is Social Bookmarking?
Social bookmarking enables you to organize and access web pages from any computer in an online "filing cabinet". When you bookmark a site using a social bookmarking tool, you can create "tags" to easily file your webpages into categories that make sense to you.
You can view and share bookmarks with anyone else you add to your network. Rather than keeping your bookmarks confined to one computer, why not share them so your colleagues can visit them and you can visit theirs too?

A thought for classroom use: Create an account for each subject/class you teach with bookmarks for students to use. You can tag these bookmarks with a particular curricular unit tag. As you are searching the web, it will be easy for you to add them to your page.
