When I log in to manage my blog, Blogger (which is owned by Google) automatically sees that I'm in China -- and very helpfully defaults to Chinese characters rather than English words for all the menus and buttons. For 1.3 billion Chinese people, I'm sure that's an essential feature -- but for a lonely American who doesn't know Chinese, it's maddening!
Somewhere, if I page through to the right place, which I can never remember where it is, I can see the single, lone English word: "English." Click on that, and I'm back in the world I'm familiar with. But today when I went to add an update or two, it took me ten minutes!
Smart folks, at Google.
