We like to share: pics with friends, stories with spouses, and the weather with our parents. In most cases we know what we want to share with whom but today’s media have a life of their own and don’t share our opinions. We share more than we think. Which information lies behind, and which comment? What do I share with a human, the network, or an algorithm? What do I share without knowing?
We take a view onto Social-Media-Platforms, how they work, collect information, and finance themselves. How can we use them without sharing “everything” and how can we keep some privacy?
