God I hate this. And it cuts across society, not just on HN or among nerds. Something like 10% or so of the people I interact with seem to just rules-lawyer their way through life as a default. "Well... as you can see in the rule book, section 5, paragraph 3, the rule clearly says we shouldn't do X, but it doesn't say we mustn't do X, so I'm clearly allowed to do X." Insufferable.
