This is an outstanding and exceptionally timely book -- highly recommended.
Two types of people should read the book ASAP -- people who:
1. Are thinking about creating a start-up, or working for one
2. Want to understand the real inner workings of the information technology business -- hardware, software, VC, etc.
I've had the distinct privilege of working with many of the people interviewed for or mentioned in the book, and I now have a fuller appreciation for what they were able to accomplish -- in many cases against all odds.
The book is especially timely in these days of "Web 2.0," bubble v2, etc. -- as the hype-to-reality index goes off the scale once again, "Founders at Work" includes many insights about why it's only a matter of time until the next "correction" kicks in.
p.s. thanks to JJ Allaire, who referenced the book on his blog (and should have a chapter in the book!).
