(On another note, it's amazing how easy it is for a comment can sound like a bit of a putdown inadvertently. Even after years of practice trying to skirt around such misinterpretations. Tone of voice and body language must be the greater part of how we avoid this in person.)
But I agree that AG should be expanded.
