What Google Latitude does is allow you to share that location with friends and family members, and likewise be able to see friends and family members' locations," said Steve Lee, product manager for Google Latitude. For example, a girlfriend could use it to see if her boyfriend has arrived at a restaurant and, if not, how far away he is.
To protect privacy, Google specifically requires people to sign up for the service. People can share their precise location, the city they're in, or nothing at all.
"What we found in testing is that the most common scenario is a symmetrical arrangement, where both people are sharing with each other," Lee said.
The software spotlights Google's fixation with mapping and location technology. Location is an important part of navigating the real world, and Google clearly sees its geographic services as a way to establish a more personal connection with customers who today use Google chiefly for the virtual realm of the Internet. And of course money is involved, too: Google hopes its mapping technology will lead to location-based advertising revenue.
