+ = FriendMapping!
Here is a very cool Google Maps powered tool that displays the location of LiveJournal user "friends" on a Google Map. It's called the LiveJournal Friend-Map Generator. To try it out, you'll need a LiveJournal username to feed it. Go here to view a few random LiveJournal entries to pick one. The map will depend on geographic information being entered into user profiles.
I can see this being a popular link from LiveJournal user blog posts in the coming days..
