I used Google Latitude to track my daughter’s location when she went away for trips.  I figure that girls need a bit more protection than boys.  Also, my son would never allow me to track him.  Google Latitude was not perfect when my daughter traveled in areas of the United States where there was no cell phone coverage.  Where there was cell phone coverage, it was very useful and accurate.  I assume this decision by Google’s alleged  oligarchy to kill Latitude held no concern for the greater good vs the company profits.
