Just seen the article at Bloomberg BusinessWeek.http://www.businessweek.com/news/2014-05-13/match-flirts-with-new-mobile-app-after-tinder-popularity-surges
I think IAC is going to deactivate Tinder soon or later, it will absorb it and merge with Match mobile (Please see Stream and Mixer features) if Tinder is cannibalizing Match mobile application.
Moreover, do you remember the scandal "IAC buys back 10% of Tinder at USD5B valuation " ?
Perhaps they had paid a bribery to someone, a former investor who wanted to recover its money back.
Tinder has no business model. It is inviable. Tinder is like Chatroulette but it will collapse like Skout. Lots of persons want to use it, but nobody wants to pay for it.
Knowing IAC since years, they plan to extract all the juicy part of Tinder, and then put it to sleep.
Match mobile Stream and Mixer will replace Tinder.
