It doesn't mean you have to get into tedious arguments with ignorant, indignant comments. (It's interesting how often those two go together.) It's enough to post a substantive top-level comment explaining what you know from the point of view of someone in the business. In the end, those tend to get upvoted; there's one at the top of this thread right now. And as moderator/gardeners we do what we can to give those more interesting plants a fighting chance vis-à-vis the weeds.
I wonder if a "badge" system could help HN. Validate professional work experience with a moderation team ("astrophysicist" because I have published papers there, or "radiation control tech" or "worked in the movie industrie" or "work at google" or whatever). You could even have more than one badge (say "work at google" and "race sailboats for sport"). And when you post a comment there is a list of all your badges below the text field an you can select one to be displayed noticeable above your comment to indicate "I have professional knowledge of this". Of course you can still post a comment without selecting any of your badges because "radiation controll tech" says nothing when discussing cookie recipes, but is an important thing to not when discussing a radioactive spill.
