Yes, I know that. And I take it a large percentage of the people that uses HN does that. But the question is, does the people that actually uses the files, knows that? The example I'm giving, is of people using PDFs with a certain format because they think the graphic appeal would make them stand out from the crowd in a very important matter (They are trying to land a new job, after all) and of people trying to find the right fit for their empty position. Neither of them know about this; but it seriously affects the outcomes.
