Which is great, as long as you're using an Android phone.
Latitude is far from perfect but usually provides enough information for my purposes. I don't really care if someone else knows my precise location, if I'm going any distance to visit someone they'll have a good idea what route I'm taking and if it all goes pear shaped they'll have an idea of where to expect to find me based on that.
