Right now I am a tech writer and the curse of knowledge is hard to break for many people. I've gotten a lot of docs from devs that are obviously just reminders for themselves of what they already know. I've had to flesh out docs that just stop halfway through a procedure.

Please just admit that writing docs is hard. Because it is. Just because there is a lot of writing going on in college doesn't mean you learn how to do technical writing, academic writing is very different.

Go to the support team and ask them what questions are they sick to death of having to deal with (hint: its usually something you would think is pretty easy) and rewrite the doc to handle it. Then watch what happens to the support questions, if that disappears you did it right.
