Helping our audience have sex with each other, now that's a brief worth working toward!

But Tinder is already doing a fine job of helping people find everyone available for a hook up. So who's left? All the people who aren't making themselves available right now.

Behold Get in Line. An all-new app by MTV that lets you call dibs on people who are currently in relationships and sends you an instant notice if that person ever changes his or her Facebook relationship status to one that might give you the opportunity for a hook up.

The app and its campaign performed quite well, generating good engagement (an average of 1.9%) with a very low CPC, just under US$ 0.15.

But the most important achievement: in just under a month, the app reached more than 2.8 million people and right now millions of potential hook ups are waiting to happen.
