Thinking today about an old, abandoned line of research of mine. How about this: when information is cheap, knowledge is expensive.
Networks
Some of my research on targeting in networks
A topic that I’ve researched a bunch over the years is the interaction between people in a network of relationships and an outsider who wants to tell or sell them something. You know something about the structure of the network that people belong to: who talks to who. Which people do you send messages or promotions to?
