@grrrr_shark The most important thing about that organization in Poland is that it's organized as a community. The people who organize stuff/give lectures/come up with workshop topics/... are in vast majority ones who, when they were students, were participants. This causes the community to e.g. have strong norms about satisfying curiosity, and have ~no age-based assumptions. Apart from direct positive effects, it also shows people by example that they can have a community where curiosity's valued.
