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.
