Google released a new widget called Google Latitude, that can keep track of your kids for you.  The widget can be used with a cell phone and your computer.  By downloading the widget to each cell phone you want to track and turning on the GPS feature you can locate you children quickly.   Now in theory your children can now no longer hide from you, but there have been some issues with this new technology.

Several groups have done some testing and found that this service is not always accurate.  The system using what is called Triangulation. Simply put the nearest three cell towers make a best guess as to where the cell phone is located.  Hopefully the cell phone is still with your child.  One group found that their children had relocated to a mall in Las Vegas, even though they had been in Atlanta, GA just 30 minutes before that.

This new free service has many advantages for small business as well.  Even though it has issues it is a great start for a free service.
