Web mapping was not mentioned; Web GIS was, quite a bit. GeoWeb? Not that I recall.
I like the proposition of "Web GIS": applying geographic information system technology and geographic information science to the universal information space -- the mature space of documents and the emerging space of data -- that we call "the Web". GIS for the Web is something that you can actually design and implement (ESRI and I part ways where the rubber meets the road). "Web GIS" is marketing, yes, but at least it's supported by solid concepts.
The "GeoWeb" proposition repels me. Asserting an existence of a "GeoWeb" distinct from the Web seems like self-imposed ghettoization. Maybe it's a matter of taste, but I'd find discussion of MusicWebs, VideoWebs, and BookWebs equally unproductive.
