Hello. I really like this idea and just watched a debate and did enjoy it.
I do like the idea of it of aggregated and real time feedback from the viewers however, My only suggestion is to make the cheers and jeers a little less intrusive. I'm just not that interested in the peanut gallery and, (for me) it interferes with the fluidity of the very short time frame people have to talk.
Great work though - I'm very interested to see how this does.
