> I try not to make fun of people for admitting they don't know things. Because for each thing "everyone knows" by the time they're adults, every day there are, on average, 10,000 people in the US hearing about it for the first time. Fraction who have heard of it at birth = 0% Fraction who have heard of it by 30 ~= 100% US birth rate ~= 4,000,000 year Number hearing about it for the first time ~= 10,000 day If I make fun of people, I train them not to tell me when they have those moments. And I miss out on the fun. Person #1, about to have a messy fun time: "Diet coke and mentos thing"? What's that? Person #2, in a delightfully pro-knowledge mood: Oh man! come on, we're going to the grocery store. Person #1: Why? Person #2: You're one of today's lucky 10,000. {{Title text: Saying 'what kind of an idiot doesn't know about the Yellowstone supervolcano' is so much more boring than telling someone about the Yellowstone supervolcano for the first time.}}

I'd have known what xkcd it is, no pasting necessary. It doesn't apply every time someone calls something old. I'm not making fun of anyone.

The other leading HN headlines are:

* GitHub shuts off access to Aurelia repository
