You probably saw the long discussion about Turin vs. Torino over at superplin: http://superplin.livejournal.com/302256.html?nc=71

and I guess I feel the same way about other uses of terms from other languages--that Americans need all the exposure we can get to the fact that most people speak many languages. I understand the feeling that using a phrase, pronounced correctly, from another language, is pretentious--but couldn't it maybe just be trying to defer to other people? Maybe not.
