Edit: in Belgium if it gives any clue
I really wish this comm took after Rule 2 of /r/whatisthisthing and disallowed joke comments. Not because "reeee no fun allowed" but because that's already present everywhere else, and it'd facilitate a lot more interesting, useful, unique discussion.
Without hyperbole, that one rule makes /r/whatisthisthing way better than most subreddits, because it doesn't let it just sink into the lowest common denominator like the rest of that shithole has.
