Numerical data services could probably work out direct relationships, but even full-text business information services might find sufficient value in regional statistical data to justify links to such a site. In return, the Web site might want to collect a constantly updated subset of articles on the economy and politics of the state it covers. They say that the price of liberty is eternal vigilance. In the Age of the Netter that has come upon us, eternal vigilance will carry a price. People will pay for services that promise to find the good stuff and bring it back with a minimum of strain on the user's day.
Nobody has everything.
Nobody even has everything good. As more and more good data comes onto the Net and its Web, Web workers will need services that find the good stuff and drag it forward. Many other users will prefer to go to small, boutique services, but even there they will expect the small services to make the necessary arrangements to cover the key sources and material outside their control. Those who do not, will not.
