The Next New Thing

All sorts of new media technologies have already been thought of and created, but living in New York its easy to get idea's from daily life. An idea I have always had but have never implemented is a social Google Maps-type website which would allow users to get together and, in a collaborative fashion, post information about transportation in their neighborhood. There is currently no single place to go for bus schedules or alternate side parking schedules in New York City. Due to the shear amount of bus stations and blocks with street cleaning, it would be very difficult for one person to gather all this information into the website. A community based wiki-like site where everyone can just place points on a map an input information about their own block or neighborhood would be quickly populated and very useful to me and others in the city.
