Just saw this Google Maps mashup mentioned on BBC World here in my hotel, so I thought I had better let other Google Mappers out there know about a mashup getting some major press play. Gawker Media has put up a Google Map that shows the realtime locations of celebrities in New York City. The Google Maps mashup is called Gawker Stalker. Users can email their sightings to a gawker address and those tips are then mapped out for other users to follow. Some are calling it the killer celeb tracking app, while others (A PR Agent was interviewed on BBC World) say that it pushes the personal privacy envelope.
