Yes, I agree: That is what chunking means in information mapping. My point
is (if you read my post again): The "seven, plus or minus two pieces (or
units)" cannot be quantified in documents. I'm not near my library right
now, but later I'll post the reference for this magic number seven and
demonstrate how it cannot be applied to information mapping the way it is
being applied now. One thing to think about in the meantime: What
constitutes a "piece of information?" A letter? A word? A phrase? A
clause? A sentence? A paragraph?
