What's the Global Masterwork Concept?

The global masterwork conception came out of the following idea. People want to be able to judge how well they're telling a story. The definition of master work that i came up with for story grid was, hey, if we were able to get a hundred thousand people to judge whether or not a story was really great and one that they would recommend to other people? That's how i define a masterwork at the highest level of coarse meaning the broadest category of kind of master work. So you can find these master works pretty easily, it's not that difficult, and then use them.
