This is really beginning to irritate me. First, Google dropped Google Reader. Now Google is dropping one of my favorite apps: Google Latitude. You can read the announcement at http://goo.gl/UaFxv.
You can find alternatives for Google Latitude, including Find My Friends on iPhone. You can also share your location with your Google+ circles, and see your friends on the map, with the Location Sharing feature of Google+ on Android and coming soon for iOS. I have looked at both but find they are not as simple and fast to use as Latitude.
If anyone has a suggestion for an easy-to-use replacement for Google Latitude that works on an iPhone and preferably also on Android, please write a comment below to let me and everyone else know what you suggest.
