Google originally created Latitude so that users could share their location – and therefore make it easy for friends and family to see where you are. Now they’ve taken this one step further. They’ve introduced check-ins so that people can show exactly where they are – be it their local corner-shop, or the new Italian – so that friends can find them even more easily. As the video shows, it looks very simple, and it will be interesting to see just what effect it has on Foursquare and Facebook Places.
