Lectio intends to provide a circular value exchange between viewers and the Lecturers. We accomplish this by having viewers tag content with emotions in order to garner feedback. We then allow Lecturers to visualize their video as a graph of emotions versus time. Please Let me know what you think also !

Here's @sama's recent Stanford lecture.

I made Lectio with a friend for a web app competition at school, let me know what you guys think!
