While I totally agree with the post, I think the tone of the delivery is likely to undermine the points made. From my perspective, for these guidelines to be adhered to there needs to be a broader buy in. 37signals are perhaps a prominent example of how this works. And if it's presented in a more pleasant way, rather than in the tone of a parent chastising a child, I think these principles can take root and become part of team/company culture.
