Once upon a time...
... communities told stories which were passed down from generation to generation. Every day, {{ yourName || "children" }} would ask diverse and interesting questions to guide what was learnt.
One day, someone decided that factory workers would be more efficient if they were all taught exactly the same curriculum, and tested on how much of it they memorized. Because of that, {{ yourName || "students" }} learnt to stop asking interesting questions and instead work out what was on the test. That left many students feeling they are no good at their subject, and removed teachers' freedom to teach passionately.
Until finally, {{ yourName || "the students" }} decided enough was enough. Why not study the things which were interesting? {{ yourName || "They" }} realized we can write notes whenever we learn something, and collaborate to build a portfolio, which friends can learn from. And started to solve interesting questions again!
