a lot of people don't realize it, but this is in fact a political question. if you establish what is basically a one-world government for how people communicate, that is not necessarily a good thing. which expressions are allowed, and which ones are disallowed? the consequences are more technical than social, sure, but they are still consequences all the same -- it's just that instead of governing the natural language, they govern the structure. can we agree on a single structure for everything?
