It's no wonder that people influence each other in many ways. If your friends or a family member like or do something, chances are you might follow them - whether it's eating a Mapo doufu, listing a song, buying a product, or using a social network. This influence can't only be predicted, it can be measured as well. And if that extra eating and spending leads to $ money, that's a value you can capture. Ninjametrics call this "social value", which is responsible for 20 to 50 percent of all game spending.
