An ambitious project, dubbed "Dropping Knowledge" takes place on Sep 09, 2006. Quote:
"On September 9, 2006, 112 of the world's most compelling thinkers, artists, writers, scientists, social entrepreneurs, philosophers and humanitarians from around the world will come together in Berlin, Germany, as guests of dropping knowledge.
Seated around the worlds largest table in historic Bebelplatz square, these inspiring individuals, renowned for their lasting creative or social contribution, will engage with 100 questions out of the thousands donated to dropping knowledge by the international public.
Using dropping knowledge's question-rating system, the public identified 500 questions as those most likely to initate open dialog on a social topic of most relevance to them. This group of questions will yield the final 100 Questions — representing a truly global sampling of cultures, themes and ideas — to be asked at the Table of Free Voices and beyond."
You can submit questions to them, and look at and rate current questions here.
Video of each participant answering the questions will be shown on the site after the event on Sep 09. The goal of the experiment/project is to ignite global discussion about social issues.
