IPhone Aplications

My friend today was telling me about an application on his I Phone called "loopt".  You can literally know exactly where someone is at any time... Essentially, your I phone plays as a tracking device.  There is a process before you can track other people.  First you must add the application to your phone.  Then you have to send requests to the people you know in order to be there loopt friend.  Once you are there loopt friend, as long as there phone is on, you can know exactly where they are.  For example: If you are loopt friends with someone, they could meet you for lunch without you even telling them your going.  I find this application way too violating.  Even though people have to allow others to see where they are, who knows what hackers are out there that can locate you whenever they want.  Technology is causing our society to be less personal and far too violating.  Technology like this should only be used by the government or organization that has everyone's best interest.  Even then, when do you draw the line of the government looking to close into our lives.  The Patriot act allows the government to tap into anyone's phone line and listen to their conversation.  The idea works great for preventing terrorist activities and other unlawful actions, but our government has begun to contradict the very principles that we hold so dearly.
