In traditional marketing you can control your message. In networked marketing, not only are you not only able to control the message, you have to be instantly responsive to what the crowd is saying. An example of this is Epicurious. The great part about it is that the users write reviews of the recipes and improve them. Epicurious has to continually react. This is continuous improvement.
The other challenge is augmenting services to create better customer experiences. Say you have your kid in a day camp, and when you ask your kid what he did at camp that day, he says "Nothing." That's frustrating to a parent. At Steve and Kate's Camp, kids wear wristbands that let people take photos and upload them into the parents' computers so the parents can see what their kids have done at the end of the day.
