Sometimes, there are thoughts, that when you first encounter them are so very arresting that your world changes in a way that's initially imperceptible, but that you know will grow in to something extraordinary. They're literally dumbfounding; there's no response to them, and you feel a whole bunch of concepts slip into a new position as they settle in to your head. That is, provided your brain doesn't spit them out like so much conceptual ambergris.
I've just stumbled across one such though. What if, by 2010, there is no address window in your browser? What if a user never has to see another URL again, ever? What if the web chooses to put its skeleton on the inside?
My god, it's full of stars.
