For the last time, privacy is not about secrecy, and it is not a battle against information. It's about dignity. It's great people get value out of these features, but do understand that to those who have not assimilated into this new culture, the idea that having to dawdle in uncertainty for 10-15 minutes while you wait for your wife to meet you downtown is some burden is ... crazy!
I thought mobile phones were supposed to solve that problem anyway. It seems nobody's content enough to agree on a meeting and patiently wait for their company anymore. Either that or they are worry-warts, or just plain distrusting. I find these new values very difficult to relate to, as I cannot imagine another reason for tracking your companion like they're a specimen of some endangered species.
