hi...i work in the software development world. i think that many people in korea learn english in a way that can best be described as "Technical English". They know enough english to understand and work with english, but they can't really communicate well if they had to in english. That's more or less been my experience, and have had other Korean colleagues tell me the same.
I think it'd be really helpful having some lessons on "Technical Korean" and in general just some more business-oriented lessons. Maybe also being able to browse the lessons not just by difficulty level, but also by subject would be helpful.
감사합니다
