Mass collaboration can be researched further here, where the article refers to these 4 important points
- being open
- acting globally
This form of collaboration certainly covers the four points mentioned above. It is open, as anyone with access to a computer can contribute. Peering means that any contributers who write "nonsense" will be sorted out and discarded by the self-policing nature of a wiki. Sharing means that certain products (in this case the product would be the new act) can be brought to the market more quickly, because the open and peering nature of the process allow information to flow more freely, with less restrictions. As for acting globally, in this case it is certainly acting country-wide.
This type of collaboration may be new with respect to writing laws, but other examples exist in recent history. They include other important issues such as the human genome sequencing project.
In fact, with regard to writing laws, there exists the potential to have an entire government designed mass-collaboratively. This is a theoretical from of governement, but, as the New Zealand example shows, in the near future we may be set to see profound changes that will change the way we do everything; from mixing music and maintaining health to determining government policy.
