I think the focus on immediate, actionable feedback is great, but I get really nervous when I see screenshots with graphs. Does peer to peer feedback happen often enough to merit such an analytical approach? Getting continuous feedback is a great goal, but it strikes me as a human (or process) problem, not a technical one.
