How Tinder will collapse? Very easy!
Facebook allows minors to use it (people from 13 to 17 years old)
Online Dating is NOT for minors.
The IAC is not going to conduct Identity Verification (ID) to screen all Tinder's members.
It seems Tinder is like Chatroulette but it will collapse like Skout.
Social dating is vaporware. Online Dating for serious daters does not need to be more social, it needs to be more effective/efficient. It needs to reduce the false positives problem and big data dating IS NOT the key to long-lasting romance. The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests". Innovations are not adding more bells and whistles to actual online dating sites.
