As Will Ferrell's famous SNL character, Harry Caray, would say, "It's a simple question" - why are you writing Salesforce documentation?
Are you doing it because you heard somebody at Dreamforce tell you to "document, document, document"? Are you doing it because... well... that's just what you do - it's part of the job description?
If those are your reasons for writing documentation, then you will never realize all of the benefits documentation can provide. You'll continue to write, and your end users will continue to ignore.
Sit down and figure out what you want your documentation to do before you write another sentence or take another screenshot. The way you create, and deliver, documentation will change depending on what you want it to do for you.
