# Turn social bookmarking and page annotation into effective learning tools (for example by including peer-assessment features). # Allow users to easily compile personal e-portfolios (for example, by combining their own works - photos, comments, articles-with testimonials others have written about them). # Let the browser suggest relevant materials (for example, by automatically identifying additional articles based on what sites a person visit or which topics they search for). # Support social learning communities (for example, by making it easy to find and connect with others who share similar learning interests).
