I just came across this really good set of slides by David Gillespie on the state of the internet and were it goes from here.
I know it's a lot of slides, but well worth browsing through. For me one of the crucial points is Clay Shirky's quote:
... tools don't get socially interesting until they get technologically boring.
The internet has become mainstream for so many people so quickly while still being in it's infancy compared to other important technological developments of the past centuries.
