I received a link from Doug Karr to test out a Beta version of a social platform called BrightKite . I always find enjoyment in checking out new forms of social media. Thanks Doug! 
Overall, the platform is pretty cool. In my opinion, the coolest feature on the site is a location generator. You can update your friends where you are in a particular city based on street address. Of course, you can do this on twitter just by sending an update but Brightkite takes it a step further and places your friends on a Google interactive map.
I like the map feature. Some might think BigBrother just got a little creepier but that is offset by a TRUST feature you can apply to friends you trust. (Something LinkedIN should figure out).
Short and to the point.
You’re welcome!
