37signals makes really great software, and their Signal vs Noise blog is one of the best. Rework is the ‘byproduct” of their working process; a series of lessons about what has and hasn’t worked for them. Their model of reducing tools to their bare minimum set of necessary features will remind anyone of Apple’s i-stuff. The book is gathering raves from all over; I confess that as usual business books leave me underwhelmed with a lot of pretty obvious advice. I do like their emphasis on good writing as the fundamental skill for the new online era.
