The way we use information is about to change. We have spent the last 40 years using computers to recreate our old 19th-century paper documents, and now we have a mess on our hands. Health care, financial information, investments, real-estate, insurance, entertainment, travel, government - all industries are incredibly inefficient because we haven't been smart about how we use information. We're starting to do things differently, and you should learn about it. That's why I'm writing a book on the Semantic Web and what it means for business people.
