SA article: Facebook Undervalued. Its Dating Service Fills An Underserved Market
http://onlinedatingsoundbarrier.blogspot.com/2019/09/sa-article-facebook-undervalued-its.html


The Online Dating Industry needs INNOVATIONS, not more bells and whistles. 
The key to long-lasting romance: COMPATIBILITY is exactly STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests or political views". 

High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
 
Without offering the NORMATIVE 16PF6 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.
