Witty, literate, and right on target, Rohlfs captures the economic and business principles of network ('bandwagon') effects in today's hottest sector of the economy. Network effects is the word du jour in the current business jargon, and many apply it where it doesn't work. Rohlfs is careful and convincing in laying out the theory, and absolutely on target in the many carefully researched examples he uses. The book is fun to read as well as incredibly useful in sorting out the wheat from the chaff. Rohlfs is the true pioneer of bandwagon/network effects, having discovered the concept almost thirty years ago. With this book, Rohlfs shows he is still the master, not only of the underlying theory but also of its practical application to a myriad of business situations. If you need one book to read on bandwagon/network effects, this has to be your choice.
