Hey! First of all: don't worry, it didn't make me feel bad–don't know about others though, of course. And I really meant what I said: I think you knew your (originally) intended audience, and there, the percentage of people is almost certainly quite a lot higher than among general HN readership. I just really like that comic and immediately had to think of it when I read that sentence. (And it's only made funnier by your intention, it really shows how true to life the comic actually is!)
But I think there is a good, general argument to be made against these kinds of sentences. I don't think anyone would ever blame you for writing about a well known thing, while at the same time there is a chance of needlessly making people feel bad.
BUT I also think that with the right "mindset", these kinds of sentences can be a good indicator to readers about what is considered essential, common knowledge among a certain group of people.
So ... I don't think you need to remove it, but wouldn't say it's bad if you did. Sorry for the long winded way of saying basically nothing.
Cool article btw.!
