This is probably off-topic for an interview with the "Director of Product Management – Revenue" but having started using Tinder I'm a little shocked at how buggy the app is for such a huge moneymaker.
I'm on iOS, so maybe Android gets all the QA... er, love.
(Also I'm pretty sure one's view of the Tinderverse is skewed to enhance the subscription, um, stickiness. Which might not be so off-topic.)
