This "flat" system sounds very nice, and I really like this rotation of responsibilities and "managerial positions" to all members. I wonder though, if the same principle is applied to the CEO and Business Owners positions as well (both in respect of decisions and profits). If not it doesn't seem that flat to me.

So preaching "flat" while being a business owner sounds a little suspicious, because you are preaching everybody about flat while standing above them.

I hope 37signals is truly different (I cannot judge since I don't know crucial details), because if at some point after ten years the business is sold to a big corp, and everyone finds himself trapped below ten levels of management, without a career path, 4 day workweeks during the summers of youth will sound like a bad joke.
