The challenge: create an account on http://zh.wikipedia.org/ , change the language (介面語言) to English in your preferences, then hope to see the navigation of pages in English. You know, the same effect as uselang=en. It won't work. You'll have to logout first even if you want to see e.g., http://zh.wikipedia.org/w/index.php?title=User:Jidanni&uselang=en in English mode. Purging won't help. P.S. my 字體變換 choice was zh-tw (no "en" to choose from there.) Tried logging out/back in. Nothing cached at my end too.
P.S.: My home wiki doesn't act that way, then again it doesn't have the 5 different choices of 字體變換 Chinese variants -- where the problem must lie. I.e., ZH Wikipedia probably assumes all _logged in_ users wan't navigation in Chinese. Whereas plain MediaWiki does not have this problem.
