The best explanation for ackerman I've seen is nate whipple's (solo-x) response to my question

"ackerman is the term used to describe a difference in steering angle between the inside front tire and outside front tire. positive ackerman, what a wrx has, turns the inside front at a faster rate then the outside front. for example, you turn your steering wheel enough so the outside front turns 7 degrees. the inside front would turn 12 degrees.

toe-out could be considered "dynamic" ackerman. lets say you are using 1 degree of toe out on both front tires for 2 degrees total toe out(you never would use that much, but it works for the example). now you have to turn the wheel a bit more to get the same 7 degrees on the outside front. all that extra toe will result in the inside front being turned more then 14 degrees. (the 12 degrees from before, plus the combined toe out, which was an obscene 2 degrees total toe out, plus the ackerman effect on that additional degree you had to turn the wheel to get the outside front to the same place). "
