One thing the network literature is focusing on is how we can get people to share information by placing incentives around information sharing-be it educational information or health information (e.g. development programs on malaria). Billions of dollars are spent on HIV education in Africa only to have misinformation spread or multiple conflicting information sources. But perhaps we're approaching this incorrectly. Perhaps the key to spreading the right information is through consumers, which have a built in network following. So if billions of people are buying stuff through groupon or amazon, or are sharing pictures an facebook, we could spread information by bundling that information with well sought after products.
