I found this merger between the two functionalities of Google Earth and You Tube very exciting. Why? Because this makes it possible to tag video to place and space. And I can already imagine very exciting ARG (Alternate Reality Gaming) propositions coming from this. For Google it means, selling really localised advertising content with mobile video. Then if they go on making the connection to the social fabric, with a solution like Jaiku (again Google) you can augment relevance of a personal search by face (nearness in social fabric) and place (nearness in locality).. Google is materialising the hybrid space in fast pace.
