Your jargon example here are words that can be learned not just from this board, but any RPG discussion, video game discussions, and even fiction writing in general.We speak in jargon all the time on these boards. Stuff like the story, fudging, hook, the adventure, sandbox, world building, "living breathing world". It's just particular jargon that seems unwelcome. Jargon that describes games like Apocalypse World, Sorcerer, Dogs in the Vineyard. It's almost like what's unwelcome is the playstyle more than the jargon.
GNS? is something I am not familiar with, I don't know the origin of, I'm not particularly inspired to read about, and when I see it in a thread I usually just close it and move on to the next topic.
I could have hung on this topic to educate myself a bit (seems to be the purpose of it?) but within the first couple posts there was already too much jargon I was unfamiliar with I deemed it not worth the effort.
