Just in case someone doesn't get the reference: https://xkcd.com/149/
Not advocating that HN isn't for non-tech-people, just saying that neither the reference nor the xkcd were out of place for this audience.
As a tech person I encounter things every day that I don't know about, and I google many of them.
Why should "non-tech" people be protected from the chore of googling ? Isn't that why people come here – to encounter things that they don't know about ?
