Do you know the feeling when you raise your hand to ask a question and the track owner announces: "There’s time left for one question only"? Of course, he doesn’t pick you to ask that question. And then the speaker disappears behind the doors of the speaker room. To make sure this situation never happened, we set up dedicated discussion zones: special areas with a flip-chart for drawing, a couple of seats and an opportunity to pour a cup of coffee or two. The discussion zone opened right after the end of every talk. That was a place to chat with speakers, ask questions about the talk or get some advice on personal projects.
