Google Maps and Google Earth build a solid geographic platform that can be used to define your world and see how it intersect with other people's worlds. You can broadcast your presence with tools like Jaiku, annotate the places you visit, expand your world with places suggested by people that have similar interests, understand the life from other countries and find what's hot in your neighborhood. Google Earth could have a new layer that's more interesting than videos, sounds or pictures: people.
