Users.

There is an enormous amount of good work in documentation, websites, wikis, ‘bodies of knowledge’ and other attempts to get knowledge out there. 

Always consider the user.  Understand what would cause a user to visit your site or read your book or document.  They probably have a specific question in mind that they are trying to answer.

Similarly, for documents, quality management, risk or competency, or anything that might need a framework developed, remember that the typical frameworks seem to be developed for the managers or contributors, not the users.

Keep the user in mind, when putting information out there.
