Zigging while others are Zagging

I keep getting the feeling that some kind of sea change is going to happen on the net - some combination of technologies is going to remix into something amazing. What form will it take? Well, it will allow people to connect in ways they could never do offline. There will always be something new to discover every day. There will be new ways to express yourself and create something unique. There will be a way to share what you have created with people you can be sure of will have some interest in it. You will be able to see who's interested in you and your creations. There will be no central control, and the emergent properties of this 'thing' will be amazing.

I know what it's going to look like, but darned if I know what it is...
