In his latest post, Kevin Kelly writes:

(There) are eight things that are better than free. Eight uncopyable values. I call them “generatives.” A generative value is a quality or attribute that must be generated, grown, cultivated, nurtured. A generative thing can not be copied, cloned, faked, replicated, counterfeited, or reproduced. It is generated uniquely, in place, over time. In the digital arena, generative qualities add value to free copies, and therefore are something that can be sold.

His post goes on to explain these eight generatives — immediacy, personalization, interpretation, authenticity, accessibility, embodiment, patronage, and findability — building blocks of new products and services that are required reading for anyone who creates products or offers services in today’s digital economy.
