The conceptual work people loosely call a web page is very real. Its not a mystifying concept. Its what people actually refer to. Kids are taught to be critical of it, ask who wrote it and what their incentives are. ("Conceptual work" is a cyc name in the cyc public ontology, by the way - that's where I got it from.) But the concept is actually common for anyone who uses the web. > MB > -- > Mark Baker.
