An electronic game designer develops an app for mobile phones that in short time becomes extremely popular — people can’t stop playing with it. Then, suddenly, the developer takes down, or removes, the app from public use because, he says, it is having a negative effect on the players. He says that the game caused players unexpected addiction — something that he could not bear to see.
What about you — can you develop an app that people would want to use all the time? What would it do? What would you call it?
