Google Lattitude Explained

Google just released an upgrade to Google Maps which lets you track the specific location of your employees, family or friends. The service, called Google Lattitude, will also let you contact them by way of SMS, Gmail, or Google Talk. Google Lattitude could have a wide range of uses if you own a business, e.g. you can know exactly where your delivery truck is at; see if your salespeople are actually selling or at the coffee shop. For friends or family members, you can see where your teenager is at or know if she/he made it through the snowstorm or their flight landed safely.

There is some concern about the "Big Brother" syndrome. Google is quick to point out that the service is strictly "Opt In" so no one can be tracked that doesn't want to be tracked.
