GEO 2.0

Map mash-ups are among the most visible & comprehensible phenomena in Web 2.0. There must be hundreds more than the accidental selection in the list below. There are only a few samples of web sites striving to go beyond the mere fun of it. I expect much more business cases to evolve around it once the telcos start offering standardized location based services.
Remarkable volume of geo activities in Holland, since recently. Is that the same anywhere else on the planet?
You'll find more samples of geo-based concepts in some of the other categories, and some more lists in ABOUT 2.0.
