Google have launched in the past week a new version of their Google Mobile Maps http://m.google.com/maps with two nice new features. First one, it now shows traffic on major UK roads, so motorways and some major A-Roads. This is great to have in the car as you can see when the traffic is about to get bad.
The other new addition is Google Latitude (http://www.google.com/latitude) which allows you to share your location with friends and them to share with you. This means that if you’re a bit bored for an hour, you can see who’s about and go join them. Of course, all this would be organised by Twitter these days, but its still a cool feature.
