I'm very puzzled looking at that page. I just can't deside where to look first. And those colors are not in good combination (as for european-man at least). You should consider of using less colors and less font-style combinations. Ok... but I am not really graphics-designer ;)
There are two answers about DNS article... Strange. Is it totally foolish or an opposite?! Or just have no reason to talk about (as badvogato said) Can't guess. :)
Actually this article is not about DNS.. It is about global namespaces. Let's say you need namespace for documents independent of storage place. Or catalog of people (on global-IRC) independent of servers.. .etc.
