I usually let blog posts from Microsoft's Robert Scoble pile up before skimming through them, but kudos to him for pointing out cool things that people do with competitor's stuff. For instance, he likes to keep on top of and point out Google Maps mashups.

Awhile back, Robert pointed out that a new site called Flagr has been launched.

Flagr allows mobile phone users to e-mail their location to the server and have it plotted on a Google Map for others to see. With the address as a starting point, you can include comments and even a picture. Site users can even subscribe to an RSS feed that will allow them to follow your flags with ease. I can see this as a useful tool for sharing your finds with others that you know... like restaurants and book stores. It would be good for arranging meet-ups with friends or keeping your family or co-workers informed of your whereabouts.

The site was setup by three young entrepreneurs from San Francisco. Nice work guys!
