Pablo links to an interesting NGO, ‘dropping knowledge’ which invites people to ask questions and later plan to host some ‘leading thinkers in the world’ to answer their questions.
See their blog- the drop, and their introductory video.
People seem to have a lot of free time and a lot of money for these types of things- could the money and effort be spent on more worthwhile cause? That’s my question.
