Well it's odd in the MMA world because basically no one used it since back in the old days of UFC, where no one really used it effectively. Then here comes Machida who was able to use it for MMA and be very successful at it. But that's the only thing everyone looks at in Machida, no one looks at the fact he has Muay Thai, a BJJ blackbelt, and wrestling skills as well.
I used to take Kempo karate, I wish I took Shotokan, IMO it's one of the better Karate styles.
As far as not watching much UFC, do you mean you don't watch MMA in general or just the UFC?
