Loopt is a mobile-enabled, social mapping service where friends can keep up-to-date with thier locations in real time. Proximity based messages can be used to detect when a friend is in the area.
Now Loopt users can integrate their address books and AIM Buddy List to share their location via SMS text or Instant Message. When a user sends an alert to a friend, they can attach their location and even a map to show exactly where they are at a that time.
"The most common mobile question in the world is 'Where are you?' and we are excited that Loopt can extend the service to a larger mobile universe," said Loopt co-founder and CEO Sam Altman. "Now, Loopt users can share their location with any friend so there'll never be any more missed social connections when everyone is on the go."
