Reminds me of how Louis CK under advise from George Carlin (I believe) throws out his material and starts fresh every year.
For creative people now, the key will be those who continue to be creative, not those attempting to ride on one creation to the end.
The same is happening in the mobile world in app stores now. People expect to get the initial offering, and then see continuous improvement through their free updates for life.
How will people manage to get their continuing creativity and effort supported in this market?
