Fiction Blog

On the way to work this morning I had this idea for a fictional set of blogs. Or more specifically, what would happen if a blog site was setup to host one or more interrelated "blogs" by/about fictional people and then the community was asked to create the entries. Basically, each entry would me a mini story painting part of the larger picture of the fictional owner. Multiple blogs could support other characters, maybe those that the first one meets or interacts with. I wonder what would the story look like in the end?
