Will the real "GeoWeb" please stand up?

On the one hand we have a "GeoWeb" that is a kind of social network, one linked not by hypertext (as are the FOAF and XFN networks) but by Tobler's Law, in which geographically adjacent web resources are your best friends (or mortal enemies). I'm sympathetic to this one, although I often disagree with the style of its evangelists. On the other hand is the "GeoWeb" of spatial data infrastructures, geographic entity registries, W*S, and other elements of an information architecture that is older than and still largely disconnected from the Web. Is one of these the real "GeoWeb", or are they just two parts of the same elephant? Can anyone describe how such a beast works?
