Ethan Zuckerman writes about a new project in West Africa, TradeNet, “TradeNet is designed to take advantage of the boom in mobile phones on the African continent, a boom that’s put mobile phones in the hands of 10% of Africans… an amazing growth over the number of people connected via wired telephony. TradeNet is designed to be an open marketplace for buyers and sellers of agricultural products throughout West Africa. The reason for this is simple: most farmers sell their goods to wholesalers located near to them.”
