I generally ignore most star ratings and look for insightful reviewer comments on possible design flaws or unexpected limitations. And sometimes from more than one place.
The reviewer who posted the 72 reviews is Rachel Friedman of EMSI Inc in Clearwater, FL. EMSI's boss (and Rachel's mother-in-law) is Marsha Friedman, a prominent Scientologist who used to be a Scientology executive.
The should at least have programmatic checks for accounts that have only or mostly 5 star ratings, or whose pattern of ratings fall outside of a normal range.
I'm thankful that I double-checked the statement that the Friedmans are Scientologists. Apparently Marsha Friedman WAS a Scientologist for years, and has now left Scientology; she wrote quite an interesting post about it here: http://markrathbun.wordpress.com/2012/03…
