I had the opportunity to interview Hyunwoo Sun in person and ask him about how he learns languages. We did the interview in English.
You can find him on YouTube and see and hear him speaking other languages like Japanese, French or his native Korean. http://www.youtube.com/ever4one
And the short video we made right after this one shows me talking about my blog, can be found here: http://www.youtube.com/watch?v=7_Gh0bj8ql8
You can find Hyunwoo's websites and what each is about by visiting his homepage at http://hyunwoosun.com/
