At least then we'll know who's behind them.
It sounds like an interesting idea, but I don't think it's going to be a competitor to Wikipedia. It sounds more like a resource for some kind of paper or essay, or an online form of peer-reviewed scientific journals. I can't ever see it evolving into an encyclopedia-form, because each article will be limited to what that individual author can do and will not be a centralized, comprehensive overview of the subject matter, but rather a specific point of view.
At least until people start building peer collaboration tools, or if organizations can actually create articles as a group of people. That could get especially interesting.
