Don't buy this book.
This book is a 2003 version of a 1995 "links page". Lots of places to go, none of them very useful.
I found that about 80% of the sites and services Weinberger talked about sites I'd already seen. Additionally hugely important concepts like Reed's law were brushed over. I wonder if the author really understands it and its implications for business.
If you want an interesting read about something happening today, try reading "Flu-the story of the great influenza pandemic of 1918". Its a totally different topic, but a much better read and you'll understand some of the thinking and goings on around SARS.
