^yeah I know she a great dancer
I've seen her dance and pop lots of times. But I've never seen a Korean person krump. The fact that it came from a girl in an idol group is even more surprising. Krumping is a new type of dance that only started to get popular only a couple years ago. It's cool too know she keeps up her studies on Hip-Hop dance and actually implements it in her performances.
But from watching those videos, that Min girl is even better than Hyoyeon! At that age in the video she's already a popping genious!
While I'm on the subject of dancing, while Hyoyeon is technically a better dancer, Yuri has much better style. Her moves are always precise and smooth. And to me style is a little more important that technicality. If only she would stay synchronized with the other girls all the time 
when i started out on SNSD i thought that Yuri is the dancer of the group, I was surprised during their MTV specials that Hyo is nicknamed as the
Dancing Queen, maybe I just prefer Yuri's moves more than Hyo before.
Min's moves are faster and lighter and looks good but on the long run, her dancing wouldn't be that far from Hyo. Good luck to her in the US debut, it's either you are destined to be great or destined to break. I'm glad that Hyo took the opposite route and joined SNSD, no matter how much those muthaf*ckas say she wasted her talent on dancing by becoming a cheerleader.
The only problem I have with Hyo's dancing is balance, I always worry about her tripping on her routines, Yuri has better balance and flow even Stephanie(The Grace) has better balance. I might regret saying this but Hyo dances much better before more than now.
