This is really rather a fun reflection.
I like Toby's analogy, but I think that it can usefully be improved.
Instead of considering publishing in English, we are publishing in the equivalent of natural language.
So the different vocabularies might correspond better to the different NLs around.
If I am able to publish in English, with a significant smattering of German or Latin for words that might be missing from English, then with a little effort, someone can more easily understand what I am saying, especially given zeitgeist, context, et cetera, usw.
However i am probably best keeping to English if I can.
On the other hand, spraying around lots of words from lots of different vocabularies makes it much harder and fragile to understand than sticking to one obscure one or even inventing my own, as it means the consumer needs to go to lots of sources to work out what is meant.

In fact, grabbing words from a bunch of different NLs is quite an easy, if vulnerable, encoding mechanism.
I have been know to write down four digit numbers using transliteration of the numbers from different languages, as a mnemonic which would just be that bit of a challenge to someone who stumbled on it.
I guess that is one reason why I am not as averse to minting URIs as some people.
Cheers
