A look at the section titles of the document reveals that a lot of effort has been made to put the advice in positive (do this) instead of negative (don't do that!), even if the document itself is clearly a catalog of donts. So it ends up sounding as if asking questions were a terribly complex endeavor, when in fact it just requires common sense and politeness. Problem is that if you're prone to commit those faux-pas, you're not going to read this document before hand anyway. Its purpose seems to be to direct offenders to it to make them aware of their faults.
