I'm not saying it's justified, I'm just saying I can imagine members doing it. Once saturation is reached, it's understandable that people aren't going to take the time to vet each submission as closely, even if we wish they would. And again, if the same discussion is played out over and over, even if it's a well-written and substantive piece, it's not necessarily a good submission for HN. And with respect to stimulating intellectual curiosity, yes, fatigue can be a reasonable proxy for flag-worthiness.
