Symbaloo and Diigo are web-based tools that provide services which complement each other well. Diigo is a social-bookmarking service--a place to store and share bookmarks to websites, web tools, and articles--and has since added the ability to highlight important passages and take notes on web pages. Symbaloo provides a place to bookmark websites, web tools, and articles in a graphical format for yourself or others. Individually, each service is a powerful tool, but used together these become powerful tools for teachers to organize their resources and present them for others.
