Ask HN: Why do many posters re-use common phrases?
4 by abhinav22 | 7 comments on Hacker News.
I have seen some common phrases so many times on here: “table stakes”, “orthogonal” and “dark patterns” are examples. Why do you guys keep re using these phrases and others? ESPECIALLY orthogonal - how is that a word that’s meant to be commonly used in speech?
