The meaning of Web cartography (see May 28th, not a permalink)
"My thoughts begin with the question, "Is the Web mappable?" or, more generally, "Are information spaces mappable?" Maps represent static entities that have a generally agreed-upon orientation. Information, though, is fluid, and attempts to diagram relationships are wholly dependent on an individual's perception. There are no universally agreed upon organizations of information."

Are web maps any useful, or not usable enough to matter? I'm interested in these questions too. Any thoughts and links, contribute them here.
