i believe the documentation and archives stored in human resources of the world are most written or translated in English, it is a widely-used communication tool as the internet, which in most pages happen to uses English as main communication language. most, i believe most countries in the globe teach more or less English in their education period, some earlier, so later, but even one learning more than 10 years can barely speak it well. it just need interactivity with people who speak or write in it. it is just a way of comunication tool or mean which one needs to adjust or learn to use, like how to use Poser :P
