The Burning Man that takes place every year in the Nevada desert gathers 50 000 for its 2011 edition; is just a 7 days bacchanal.
The festival is based on money free model where everything participants bring must be share with others
It´s interesting to see what really pushes people to create, for free, extremly elaborated structures. They are not driven by money, but more by a social recognition to others; creating a complex structure gives them a status. Creativity and social identification drives people better that financials incentives.
"People want to be inspired, not lectured. They tend to respond better to humour and gentle reminders than they do to dictates or presumptiions of guilf before innocence"
