As a software architect building a scalable web platform that will be providing communication services for its users, this book helped me quickly get an understanding of some of the key ideas, tools, and technologies that will go into the system. There may be many different definitions for "Web 3.0" but I agree with the author that no matter on its final form a big part of Web 3.0 will be more interconnectedness and more intelligent data processing and retrieval. Web-related technology is too broad and changing too quickly to be an expert in everything but as an architect I need to know enough about the different options in order to use them effectively. The text and examples from the book are clear and concise and gave me the knowledge I needed to improve the system design and with the new background information I now know what to research further.
