NO INNOVATIONS SINCE YEARS!!!
http://onlinedatingsoundbarrier.blogspot.com.ar/2013/01/no-innovations-since-years.html

The Online Dating Industry is performing like the Pharmaceutical and Cosmetic Industry before the USA Food and Drug Administration was created.   There is no/weak Legislation, no ID verification, low reliable background checks, no Quality Norms.
 
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.

The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".

WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!  No actual online dating site  is "scientifically proven" because no one can prove its matching algorithm can match prospective partners who will have more stable and satisfying relationships -and very low divorce rates- than couples matched by chance, astrological destiny, personal preferences, searching on one's own, or other technique as the control group in a peer reviewed Scientific Paper for the majority (over 90%) of its members.
but no one can show you a list of compatible persons like this:
( for a prospective male customer / sample but calculated with real values)
“Over 1,000,000 million women database, here is the list of the 12 more compatible with you. Notice that woman#1 is the most compatible with you but she could be more compatible with other men right now.
woman#01 is 95.58476277% compatible
woman#02 is 95.56224356% compatible
woman#03 is 95.52998273% compatible
woman#04 is 94.18354278% compatible
woman#05 is 93.00453871% compatible
woman#06 is 93.00007524% compatible
woman#07 is 92.99738452% compatible
woman#08 is 92.37945551% compatible
woman#09 is 92.29779173% compatible
woman#10 is 92.27114287% compatible
woman#11 is 92.19515551% compatible
woman#12 is 92.12249558% compatible”
