This is a bit surprising considering some people consider Google Latitude to be an invasion of privacy. The service basically reports where you are located on a Google Map by reading your IP address or your mobile phone location. Vic Gundotra stated that ?more than a million? mobile subscribers signed up for the service within the first week of launch. Google launched Latitude in about 27 markets around the world and supports multiple mobile platforms. The service launched on February 4.
Using Latitude, you can monitor the status of your friends in real-time, chat with them using Google Talk, or call them through the user interface. One of the limitations of Google Latitude is that the IP address location isn’t always accurate. For example, my ISP is based in Detroit so it will report me as being there instead of in Ann Arbor. Regardless, one million within one week is definetely bragging rights for Google. If you haven’t signed up for Google Latitude yet, check it out here: http://www.google.com/latitude/.
