- It gives a new perspective over the local data. - It's easier and more fun to navigate and browse. Many people will also explore the maps just from curiosity. See [platial.com...] (I'd be happy to send screenshots from their beta, msg me). - It saves clicks - u can see the relevant details (like reviews) in the bubble, instead of clicking each link - If you are constantly on public wi-fi (laptop/PDA) - that's the preferred view to use. - Moreover - Google maps remixed with local data are very powerfull for the wi-fi surfer. - Not to mention tourists and movers to new places.
To conclude: everything is revealed, in a cool visual interactive framework.
