Is aikido good for self defense?
A high-ranking instructor whose name escapes me once said something like "Aikido works; your Aikido doesn't."
Aikido gets a lot of flak from other styles about its effectiveness, but I've always thought that was silly. IMO, Aikido will stop being effective when nikkyo stops being painful, and I don't see that happening anytime soon.
Oh, and I agree with Gregg, that was very nicely said Mary!
