This article forgot to take into account one HUGE factor in people who use the rating systems. ATTENTION SPAN. Yes. People don't have the attention span to independently analyze 5 different scatter graphs of 5 similar products. Sometimes the scatter plots can be actually more confusing and less informing than something simple like a histogram. I firmly believe that people's attention spans are more captured by things like star ratings and histograms. If they get past the stage of their interest being captured, THEN they read the reviews to find out more in-depth information and opinions. I think it's a system that works well, as Amazon has shown.
