What bothers me the most is that comments will float to the top of a link that's an arxiv paper or uni press where people will talk about how something is still in a prototype stage and not production yet/has a ways to go to production. While this is fine, that's also the context of works like these. But it is the same thing that I see in reviews. I've had works myself killed because reviewers treat the paper as a product rather than... you know... research.
