Query: Te main content not updated much since the last edition

It is a very good book for anyone interested about high tech startup. However, I found that the main content, especially the case studies, have not been updated much since the last edition. The only change seems to be the tables outlining the growth of valuation of Yahoo and Netscape. There must be something more to add to the book about them and other successful internet startups.
