Why Buy the Cow? is a book by Subrah Iyar, co-founder and general manager of WebEx, that sets out to explain the Software-as-a-Service (SaaS) movement and Web 2.0. The title refers to an analogy used to describe the new generation of software vendors who, in effect, sell milk instead of forcing customers to buy cows to milk themselves.
Appropriately, I was pleased to discover (here), this book about web-based collaboration and software resulted from the collaborative efforts of multiple contributors and editors using a wiki and numerous web meetings. It’s even published on-demand by lulu.com.
