IMHO JAMJTX's reasoning makes it understandable why many people choose to capitalize the word aikido. It will still not make it correct from the eyes of mainstream society, though.
(Geee! I started a thread on language usage, and it has gotten kind of popular! I am kind of a language usage nerd, although it does not show when I have to use my clumsy second language... and so I am very happy :-)
EDIT: Note that the Aiki shrine is capitalized above because it is the name of a building, not because I think aiki should be capitalized.
