to be honest, I don't think Kara's made it yet. They've definitely earned a name for themselves, and they are getting more face-time (CF finally!) and appearances in various shows, but they're far from being "firmly" established, especially with the girl-group fest that's going on. Rock U/Pretty Girl/Honey were mildly popular, and Wanna/Mister got them more attention (because of the "butt" dance more than anything). In my mind, they haven't given us something that really says "WOW" musically, and with the end of Revolution album promos, they've done away with alot of potential for other-song promotion.
I'm not trying to be mean, because I like Kara more than the other groups out there right now (not just for their music, but personality-wise, along with their hard-working character), but I hope they don't become complacent and think their slight popularity now will carry them. Kara! 화이팅!
