The idea of a completely open company is interesting. Balanced is not completely open (yet?) because there are still financial info and salary info that is not public. Gittip is an example of a fully open organization <a href="http://gittip.com/" rel="nofollow">http://gittip.com/</a> where every single aspect is open. Personally I work at Mozilla which is not fully open but we strive to be as open as possible. For example, salary info is only public for board members, not all employees. Also, Mozilla needs to keep severe security bugs private until all patches are out in order to minimize wild exploits. It is definitely a challenge to be a fully open company.
