The world’s knowledge is now at our fingertips. The net offers an inconceivable wealth of information flooding in on us in real time: breaking news, thrilling stories, and groundbreaking studies. It gives us insight into foreign cultures, new perspectives, different opinions. It lets us get involved, look for like-minded people, find supporters or organize protests. And it helps us find our way around new places - whether we’re on vacation or want to move to a new country. In the digital age, access to the Internet is one of the most important prerequisites for social participation – and using digital media competently is becoming as important as knowing your times tables. That’s because the net also confronts us with other things: fake messages, propaganda, insults. There’s no real filter - so facts appear next to fake news, and war reports play alongside cat videos. In a digital world full of fascinating possibilities, we need guidelines to help us recognize what is important and what is right – as individuals, but also as a society.
