I've looked at used some of the online tools from 37signals, such as Writeboard, Ta-da List and Backpack, and so I was interested to learn that they've written a book about their philosophy and company ideas. The basic theme is how to start out in a new technology venture, using the contrarian approach of providing less, releasing early, and above all - staying small.

"All the cash, all the marketing, all the people in the world can't buy the agility you get from being small."

The book is available online here. You can also pay US$19 to get a copy in pdf or US$29 for a paperpack copy. The online content is exactly the same as the printed version, which I'm actually contemplating purchasing ... I always find it easier to make my notes directly in the book :)

"Keep it small. Keep it simple. Let it happen."
