Correction: Hacker News is an American-founded site with international community of users. That's not a site for Americans where the rest of the world just comes to watch. Or maybe I missed a point in the guidelines...

I'm not talking about currencies. I'm talking about sentences like "if you move to the east, you'll earn...", "in the south, it's..." in conversations with no prior indication that it's just about US and "the east" means "the east of US" and "the south" means "the south of US". Because US is the whole world and there is no need to clarify...
