Evolution of perceptable information: Solid -> Liquid -> ... Gas?

I'm finishing up The Social Animal, by David Brooks. One phrase caught my attention because it illustrates current transition from documents-centric computer interfaces to stream-centric ones:

The unconscious treats information like a fluid, not a solid. (p.239).

With twitter, the humanity's unconscious found a way to satisfy its need for ceaseless stream of background chatter: crowd-wisdom, crowd-sourcing, crowd-everything.

I wonder, what would be the next step in this direction.
