Great points. I'm definitely interested in allowing students to provide more in-depth feedback.

Participation is a much trickier issue. In the classes that I tested in about 40 - 60% of the students actually used it. I was thinking of weighting the confusion 'votes' based on 'active' users.

I'm hoping that through feedback form professors I'll be able to add features that make it more worth while for students.

That's a lot more participation than I would have guessed, that's pretty awesome! Thanks for the info, and I look forward to seeing this getting more widespread use :)
