I think it is better with karate, along with the other striking arts being posted on the martial arts board. Like ironfoot says you get different perspectives.
Karate is made up of
basic techniques (post on martial arts talk and gain perspective from boxers, kung fu, mauy tai etc;
sparring (post on practice/ompetition fighting)
kata (post on kata and application)
With those three plus the self defence section I think it's pretty much covered personally.
