The Google+ now allows you to automatically share your location with those that you choose. The feature is very similar to the idea behind Google Latitude. However, now the sharing is integrated into the Google+ profile.
There is a brand new “Location Settings” option under the account settings for Google+. Under this is a check box to “Enable Location Sharing.” As with everything pertaining to Google+, this setting can be made available only for yourself, the public, extended circles, or specific circles.
