Their blog and their book is the SEO, product placements and self-promotion in the first place. Do not confuse it with something like selfless and sincere help to the community. ^_^ Update: Dear anonymous coward-down-voters! Face the reality - 37signals is a successful business, and it looks a lot like that of MySQL - lot of hype and really good, well-written texts, which means big and active community. Do not assume that they know only programming. Those guys looks like well-read and more or less familiar with Eastern, philosophy. Most of their advises are just adaptations of some well-known Zen (and from other branches) principles. ^_^
