37signals can do this because of their hiring practices. They need to be extremely picky with the type of employee they hire. Their hires need to be able to function within their unconventional structure. This type of information doesn't translate well to most other companies. I hope 37signals' audience gets that. For software startups, many of their ideas are exceptional and it's fantastic to see real-world examples. For already-established companies and companies that can't be as picky as 37s, testing this type of structure seems unnecessarily risky. I believe 37s has addressed this in the past, and Jason has in his Inc. writings. I just hope people are paying attention.
