As a senior engineer, this hits home for me so hard. I use the documentation hack all the time. Junior engineers are frequently amazed by how much I know. My secret is that I know where the documentation is and when I learn something, I add it to the docs. Half the time I answer a question I have to look it up again in the docs. My frustration is that most engineers seem allergic to updating docs. I think this is some combination of (1) don't know docs exist (2) feel confident they can write authoritatively (3) falsely believe that docs that aren't 100% correct are useless (4) don't like to write or don't feel rewarded for writing. For different engineers, it's a different combo, but the net result is still that the docs don't get updated as much as they could if everyone pitched in.
