Kris Krug's got a very nice interview with Doug Rushkoff at his blog.
Here's a taste: "Currently, we innovate for patents, and create for copyrights. These are the only ways we have come up with so far to reward innovation. And it eventually requires that some form of artificial protection be enforced. That’s because we have an economic reality based on scarcity rather than abundance."
And another one: "It’s the adherence to quarterly, short-term goals and shareholder expectations that have led corporations down their profitless, innovation-lacking paths. They look to decrease the bottom line without expanding the top line. So they can't make investments in long term strategies like real research and development, or creating a culture for their products. They can’t look to the longterm impact of their products without sacrificing what shareholders believe are their own short-term interests. Shareholders want the stock to go up, now. That’s all they understand. And the stock only goes up if revenues go up that quarter."
