Re: What makes Aikido aikido (to you)?
If you get a chance to read Tomiki's "Judo, Appendix Aikido" (damn, that's a catchy title!) it's well worth the time. I found it interesting that he seemed to consider Aikido to be the place for budo and martial efficacy and judo the place for sport and all the personal development that has to offer. Different methods to explore common principles and methods (that's my reading of it anyway). That article you link is one of my favorites. It's simple, well written and doesn't make any wild claims.
