Google Latitude

Google Latitude lets uses to manually turn on and off the tracking software; thus gives users choice when they should be or should not be seen.  It also lets users to choose the people who should be able to locate them.  http://google/latitude.com uses global positioning system, wifi, and cell tower location data to find/track/locate people.  It is amazing how you can use this website to find people or let people locate you.  I thing this can be very dangerous too, if you have someone out to get you and they can track you down by using google latitude.  It would be helpful for certain businesses but me as a student I probably wouldn't use goolge latitude again.
