This sounds like solid and worthy research. I would be especially interested to see your Amazon words v. stars results. Just off the top of my head, I can see a ton of uses for your research -- More accurate real time political polling / Better product assessments across the vast internet landscape for both designers and brand managers / Policy analysis for new policy proposal and communication evaluations. This has fantastic potential. Please show us the testing and results when you get to it. Thank you for sharing.
