GEO 2.0 - consolidated

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.
You can find more samples of geo tracking in some of the other categories.
