Tinder offers "social discovery, gamification, location and messaging features."
Those Tinder's founders were/are only puppets from IAC's Match Group.
My bet: IAC will put Tinder to sleep soon or later.
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 to screen all Tinder's free users / members.
It seems Tinder is like Chatroulette but it will collapse like Skout.
When the IAC Personals bought OKCupid (3+ years ago) for an astronomical amount of money, the OKCupid team had the task to copycat Badoo, but they failed in that mission. IAC Personals backed Tinder instead, as the copycat of Badoo. Tinder is only a cheap marketing tool to send prospective clients to Match and make them paid there, but it seems there is a divorce between Tinder and Match just now!
(Tinder cannibalizing Match)
Perhaps the IAC will "discretely bury" Tinder soon, it will absorb it and merge with Match mobile (with Stream and Mixer features) as soon as possible.
Please see this information from Alexa and Compete, they show their sites reached operating ceiling!
AlsoIAC's Q3 2014 Supplemental Financial Information and Metrics
Worldwide there are less than 7 million paid members (adding up all the ones at eHarmony/eDarling/EliteSingles, Match, Chemistry, Meetic, MeeticAffinity, OkCupid, PeopleMedia's Communities, PlentyOfFish, Parship/eCift, and others).
They do not want to innovate. They want to squeeze their big databases to get all the juice (money) from the wallets of the daters.
