what you see may not be what you get

one thing i dont understand.
why do people like to publicise their whereabouts?
like who will be THAT interested in their life to know where they are at what time?
especially when they are at home.
what is so special about being at home that you have to publicise it?
are you encouraging stalkers?
i prefer to keep my privacy.

sometimes, social networking sites are abused and we became slaves of it.
