Feedback on a new 'paperless classroom' tool for teachers

Below is a website that was designed to help teachers collect and organize web content with desktop content in a way that is useful for learning. It basically allows teachers to create 3-ring binders for the web and use them to share with students or colleagues or as a way to organize class resources. Would love to get feedback from teachers about the site and see how it can fit or not fit with your 'paperless' classroom goals or your integrating technology in the classroom goals.

Appreciate your feedback.
