I want to add that the best coin to copy for this is Devcoin. They have a model where when I block is mined, 10% of the coins in that block go to the miner, while the other 90% goes in the wallet of a writer.
If I am a good writer, why would I pay out 10% of my income? That is more expensive than credit card charges!
Again, don't confuse money for wealth. Writers produce wealth in the form of the stories/articles/whatever they are writing. The currency used to trade that wealth only matters as far as:
+ What can the writer buy with it
+ If the writer saves it, will it buy more or less in the future
