I agree. I think that a very simple, single function service like this could be useful. You know exactly what you are sharing and who you are sharing it with.

I agree. I think that a very simple, single function service like this could be useful. You know exactly what you are sharing and who you are sharing it with. In the past, I've been known to take a screenshot of my open maps application (with my location shown on the map), and sms that to friends to let them know where I am if I didn't have the address handy. This is clearly a better solution.
