Re: Ki Society Aikido
The "one true way" of aikido, not to be confused with the "one true way" of aikikai, "one true way" of Iwama or shodokan or yoshinkan etc. etc.
Basically its aikido with (normally) a slightly different methodology than some other forms of aikido which is decried by some, lauded by others and sniffily referred to as not officially acknowledged by the founder - just go to the dojo, try it out and see if it fits what you want. Normally the only problem with Ki dojos is the people are so irritatingly nice you want to hit them just to see them angry (I should know - I is one, but without the niceness)
I know we're being flippent, but perhaps you can tell us what your interest is so we can provide a better answer. Unless the question is purely a "what is it?" in which case the excellent links provided by my august colleagues should cover what you need.
