I’m the sort of person who says out loud—“lalala”— when someone talks about a piece of entertainment I’ve not yet seen/read.
However this bit about mice in HGTTG isn’t a “massive spoiler” for a book full of similar jokes or inversions. It’s just a joke, and not revealing of a major *plot twist*, which is the generally accepted definition of a spoiler—there are more things like this in the book. By the end, hardly one is more shocking than another.
Now, if you want a real good spoiler, M. Night Shyamalan’s “The Sixth Sense”... lalalalala
Thanks for not spoiling btw, I should add 6th sense to the list, heard the title before but didn't know it's by Shyalaman
I'm going to assume you're referring to online spoilers (in text). Most people I know don't have patience to speak about books in person.
It really has to do with the community and their standards. Over at Metafilter.com that community is focused mostly on culture and entertainment topics. They're conscious of spoilers. Posters are hoping to introduce the community to new content or to think of older content in a new light. They want to share, entice and peak your interest to seek, find and enjoy the content they're posting about--if they tell you the punch line, then they've ruined the joke. And this permeates to the comments as well.
What about HN? I see a lot of science, mathematics, engineering, technology, computing topics. What's the community standard for these disciplines? Prove you did the work. Share your sources. Explain what you mean. Quote. Link. And this permeates to the comments as well. Overwhelming detail is the standard. It's a feature, and not a bug (lalalala).
But if that explanation is too much of a stretch for you, let me share the immortal words of Chris Farley, "Remember when... [...] that was Awesome!" https://youtu.be/iK-04wOy2BM?si=mym_q0ZxxfD887a1&t=46
I can't believe this needs to even be explained but the reason spoilers are spoilers and are discouraged is that some people sometimes save something very good for later (and guess what that's disproportionately the classics because they tend to be good) and some people are too young and have not had time to read all of what you read (even if they wanted to for some reason)
In this case additionally the spoiler (detailing plot point and revealing what work it's in) was not necessary at all
