Meet Sharon Carpenter, an exemplar for wannabe celebs | Rebecca Nicholson

She's a safe pair of hands who asks the questions and fills the airtime

Hardly a day goes by without real life throwing another offering into the pot of potential Black Mirror storylines.

The latest is the general knowledge app HQ, played live on smartphones, like a quiz show, at set times of the day, with prize money to be divided up between the players who make it to the end of 12 increasingly difficult questions. I've never managed to get past question six, but I know someone who won $150. The game has already been on the receiving end of a number of controversies, about its investors and creators, but that doesn't seem to have dented its appeal. While the quiz plays out, there's a rolling comments section underneath it, like a demonic Twitter feed that it's impossible to take your eyes away from. Not only is it Black Mirror-ish, it's a bit Clockwork Orange, too.
