Very interesting article. I prefer techniques that would have value in a street fight situation. This usually means those with fluid, efficient movement. A counter attack must be fast, so multiple steps and choppy broken movements simply won't do. I believe that effective use of atemi during your technique can turn an otherwise ineffective move into a very potent one. Stunning, or softening an opponent up with a strike can leave him vulnerable to almost any wrist lock or throw.
Aikido also lends itself to non-lethal means of self-defense and control over others. In other self-defense systems, like Krav Maga, the motto is beat them into submission. WIth Aikido, you can submit people through the application of temporary pain, rather than permanent injury.
