I’m currently reading the book Rework, written by the guys from 37signals.com, makers of Basecamp and other very nice collaboration tools.
This book is really a must read for everyone that runs or is planning to run its own business.
Included is a interactive mindmap in PDF format (with Flash embedded, needs to be viewed with Adobe Reader) that summarizes the book. I don’t know the original author of this mindmap, but all credit should go to him/her.
Use the download link to get it, because posterous can not convert this type of PDF to something viewable.
