Overall it seem a clear easy to read policy that most employees would understand and be able to follow. In reading the comments on Mark’s blog readers have certainly pointed out areas for improvement, however that would be the case for most policies. Thomas Nelson Publishing have been going through the same process via Michael Hyatt’s blog Working Smart and have revised the policy to be more readable.
I hope Mark and the team at Plaxo have taken into account their organisation’s culture when developing the policy. For example Microsoft seems to have taken into account their culture with the very general “Be Smart” but that would not work for all organisations, Sun has done the same thing.
