The profile asked me for my first language, which, in my case, is Korean. But then it displays my "Language" as Korean, implying that Korean is my preferred language. This is not true; although I am certainly fluent in Korean, my English is somewhat better.
Instead of "first language," wouldn't it be better to ask for preferred language, or perhaps primary language?
Even better, shouldn't there be an option to choose multiple languages for people who are fluent in multiple languages?
