When I first read "7x3," I thought, immediately, that
it was a reference to facets and orthogonality. But,
more to the point, I would think, at the least, that
any numbers related to describing the structure of a
given vocabulary would, in great part, indicate the
adequate to thorough coverage of a domain.
It seems that applying the "7x3" or "7 + or -2" rules
focuses primarily on, or biases in favor of, the user
at the risk of losing sight of content warrant.
