Our Geo Messages project has been updated again.
Rather than let social network monitor your location (Google Latitude) or share your location info within some social circle (Foursquare check-in etc.) Geo Messages approach lets you share location data on the peer to peer basic. You can share your location info just as a signature to the standard messaging (email, SMS). And what is important – shared location data (map) does not contain your identity. Your ID (name, phone) is in your email (SMS) only. The shared map does not reveal anything about the author.
By the same principles you can also share location info with your Twitter and/or Facebook friends. The latest update includes Where are you now mashup too. It lets you request location info by email.
