On another note, I'm interested in knowing how "confusion" is gauged - I suspect it might be picking up those asking for clarification as well as those who are truly confused. There seems to be too much confusion for this crowd (unless it's only measuring me).
Very cool - would you mind elaborating on the tools you used to analyze the sentiment? Any open source ones / is the source available for reuse? Would love to apply this to other areas.
Cool tool! One thing I really hate about it (in an entirely exaggerated way) is how the stupid filters reset themselves every few seconds if you're in live mode.
