I don't interact with the PDF output myself, but I can compile and email PDFs if I need to send work over to people who do not wish to receive LaTeX themselves, a fact I used throughout most of my high-school education, where LaTeX knowledge was rare. This is why I eschew formatting where possible, I can do enough to make my symbols look right and be understandable to a sighted reader not familiar with LaTeX, but not necessarily to make things extra pretty. Not actually seeing the output makes it a lot more difficult to check your formatting work.
