A great community guide & Google Maps App - Here is a great use of the Google Maps API. Chris Fairbanks has established a community/city guide for the Williamsburg neighbourhood of New York City called 'Williamsburger'. Currently there are 5 maps displaying information about the businesses on that street, plotted on Google Maps. Browse restaurants by type, read reviews and view the menus of the restaurants that are listed. You can track the progress as the community comes alive in this great Google Maps mashup!
