alt Hacker NewsWith all (a lot?) of this language, it's not that it's using new turns of phrases, it's that it will use the same rare but valid phrases over and over. Everybody has their own speaking patterns. But imagine if one person's idiosyncrasies were everywhere. That's what's happened here.
That doesn't seem that uncommon to me. A lot of people have phrases that they commonly overuse. Sometimes quite dramatically. I wouldn't be suprised if that's even more the case when communicating complex topics since, at least personally, once I find an approach that lets me communicate some difficult part of an argument I tend to reuse it.
