No, I'm not kidding and yes, I am a Romanian; from Cluj-Napoca actually. Why would I be kidding? I know few developers which have difficulties with the English language. I know many that know the difference between "who" and "whom" or between "color" and "colour". I can't account for all, of course, that's why I wrote "the average", in an attempt to group them by their skills. Maybe I did exaggerate the part with "most americans", but I've certainly seen enough examples of English being misused.
