So complete is our moral collapse that we now have an app for consent

The smart phone has well and truly colonised the dating game. First it was apps like Plenty of Fish, which brought long-standing websites on to the mobile platform.

Then, it was Tinder, the app that lets you decide whether you like or dislike some-one based only on a photo (a fine basis for an introduction). Its developers boldly claim: “It’s like real life, but better.” I certainly hope that’s not true.
