Yeah, I'm also a Korean wave fan...
And to start talking something about this, I think it's better to choose the language as the first topic.
If your are one of those Hallyu fans, I think you could start learning the Korean language trough this:

Those links are the ones I've found of my personal research... I couldn't imagine I'd have found so many resources for learning their language, I thought it would be as Japanese and I wouldn't find anything useful but it was the opposite, fortunately...
So Korean is a very commercial language and easier too, compared to Japanese, Chinese or any other Asian language... I think. If you wanna understand Hallyu world it's better to start your lessons right now ^^
