Excellent post from Ben McConnell, addressing Thomas Friedman's concerns about the ability to browse his book online for free.
You raise two questions that thousands of content creators, manufacturers, resellers — just about everyone — grapple with every day:
1. How much of my product/service do I give away?
2. How do I control the aftermarket for my product?
The second one is a funny question that way too many companies are concerned about. Control? That's the job of your customers. Let them do it.
