Hmm... often I think it is nice to have a standard term for a phenomenon so that people don't have to figure out how to express a certain concept each time and then hope that everyone else can follow. Language also has the advantage that insofar as we convince people to adopt our language, we draw them into our worldview.

I usually find these "lists of jargon + replacements" quite bad (i.e. include many things where the distinction between the term used and the suggested replacement is important and useful, and/or seem to misunderstand the terms they're suggesting replacements for, and/or include many things that virtually nobody says except maybe as a joke).
But I think this one is pretty good and mostly agree with it.
My only disagreement is with the order of magnitude thing. I love orders of magnitude talk. I think it's really useful to think in orders of magnitude about many (most?) things. If this means I sometimes say "one order of magnitude" when I could just say "ten times" so be it.
