eHarmony is ONLY a 19  years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test used by eHarmony, had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons. It is a HOAX, a FRAUD to use the Big Five normative test in year 2019. 

The Online Dating Industry is selling elixirs, tonics, snake oil liniments and other patent medicine and performing like the Pharmaceutical and Cosmetic Industry before the USA Food and Drug Administration was created where any player can make any claim without any credentials. 

The Online Dating Industry needs INNOVATIONS, not more bells and whistles.
Lack Of Innovation & Decadence can summarize the Online Dating Industry.
C-Level executives are more worried about their golf scores than their company’s long term strategy and innovations.
C-level executives are cooking barbecues under the water (selling smoke) and not paying attention to latest research from Academics which could be beneficial for the Online Dating Industry.
