~~Having come from a jujitsu background I still don't understand why, whether we're using a deep or shallow hip technique, everything's called 'koshinage'. Sometimes we're exicuting O goshi, tsurikomi goshi, uki goshi, uchi matta nage, tai otoshi, etc.
Maybe it is proprietary. I use a Dell, some people use IBMs, others use Macintoshes. They are all machines we call computers. I think the same thing kind of applies to naming techniques; some people just like a little bit more description, or others don't want to associate what they do in Aikido with what others do in Judo.
