I've read the article, as I'm sure Ron has previously, and I still don't see anything in there about Shioda eliminating ki from the curriculum. To be sure, Yoshinkan aikido is quite different from Ki Society aikido, but the idea that Shioda eliminated ki from his curriculum doesn't stand up to even a cursory examination of his books, lectures, and instructional tapes. In fact, going from their published writings, Shioda mentions ki even more than Morihiro Saito.
And I say this as a former Iwama practitioner who's never stepped a foot into a Yoshinkan dojo.
Oops, sorry I think I may have submitted the link a little out of contrast. I was trying to make a point more of who created Modern Aikido and it's methodology. Again forget the post.
