@danilo on past form nothing will come of the new web. Unless it does :-)
The root cause is what economists term "coordination problems". People not getting their act together on their own. Which creates room for opportunists to intermediate and benefit immensely. This is a social flaw as old as the first temple collecting grain tax. Capitalism is literally built on virtual intermediaries we call "companies".
The digital age makes coordination easier but we haven't seen much good from this yet
