There seems to be a hell of a lot of mileage recently in grabbing onto a technological trend that's owned by the people and talking about how it's going to rip down every aspect of the old world order and replace it with a brave new world without large media / business / governmental organisations. You find a trend and you shout about it in public, waving a fist at the big boys as you threaten to drag them down to their knees. You get invited to a lot of conferences this way. You may even get a book deal. Large companies will invite you to talk to them about why they should employ you to protect them from the future you've said will destroy them. wrd.
The world is changing really rapidly - technology is having a significant impact. I think the idea of tens of millions of individuals expressing their opinions in public is profoundly moving and important and is likely to have all kinds of repercussions that we can't possibly foresee at the moment.
