These will probably be stupid questions, but here they go anyway. Is there any point to Latitude beyond you and your friends sharing your location all the time? Since I have no friends that are currently using Latitude, is there any point to me using it? How would I go about adding friends to Latitude? Will contacts in my phone automatically be added if they start using it? I have to imagine it would drain the battery faster than not having it on, am I right on that? That's all I can think of for now. Thanks in advance for your patience.
