It is nice to see when a new feature appears that the people behind it is warning you of possibel bad side effects. Like when you have your android device exposing your position (using the build in GPS). Today I recieved such a warning from Google by e-mail:
To protect your privacy we would like you to know that Google Latitude is running on your Android-powered device and reporting your location.
If you didn’t enable this or want to stop reporting your location please open the Maps app on your device. Go to ‘Menu’ > ‘Latitude’ > ‘Privacy’ and change your privacy settings.

Thank you Google! On the one hand you use the position information of the visitiors (first asking them if it is okay!) and on the other hand you remind people that a potential risc exists! Very cool done!
