What do people want? That's a big question in any business venture or job, and one that is often surprisingly hard to answer. In many cases people just hope people want what they make, or hope to convince them they want it (that's what marketing departments are for).
Right now in the age of DLC, e-comics, and online purchases from stores with gigantic virtual inventories, we've got an incredible opportunity to find out what people want. We'd better be ready, because the meandering-forward economy with its eBooks and virtual stores and fermium games is going to be a giant learning opportunity.
