Chuck's description clears up some confusion for me, and although I know that the NGA folks are really clear, proud, and honest about their lineage, but what of folks who are not? Is that "aikido" although if you walked into the dojo you will see them doing some techniques that look like aikido (especially to the untrained eye)? I'm talking about people who appear and present themselves to be connected to someone but in reality they are not. (Yes, this is a real group and comes from personal experience. I have spoken to people about this group before, they know who I'm talking about.)
Are they "my style mish-mash don't know if it's Ueshiba-ha or Takeda-ha" aikido?
Does unknown or no lineage = not aikido?
