The main problem with the English language speakers in ANY other language section is that by far most of us (And I definitely include myself in this) only actually speak English with any degree of facility.
Chinese is certainly the most common native tongue (Simply by virtue of the fact they have the rest of us outnumbered
) but English is probably the most commonly spoken tongue. As such, English speakers can afford to be (And often are - again I include myself) lazy when it comes to learning other languages.
It also means that the other international members (Who speak a wide variety of native languages, I know) usually have one 'common tongue' - which is English.
Just the way it is, right now
