Go back twenty years to 1993. When you wanted to complain about a product you wrote a letter to an editor for information, referred to magazines, or to your local retailer. Today, customers and users are in direct contact with producers and in direct competition with journalists. The leadership of opinions has shifted dramatically, but many people still ignore this situation - especially the journalists. Boris Schneider-Johne takes all of his knowledge from thirty years as a customer, producer, journalist and marketer, and explains the psychology of app store ratings, the power struggle over review embargos, the potency of numbers, and the emotions about technology. Warning: may contain current brain research, nostalgia, cynical remarks, usable tips and interactive experiments with the audience.
