The Friend density map is an interesting one. It shows you where the highest concentration of your friends is. It’s a good idea when you’ve got friends spread around the world as we do. It’s a shame it’s limited only to the US at the moment. I can only see six percent of my friends this way.
I sent a quick message to the creator of the API and I hope he resolves this issue in the near future.
As I was looking through the applications I found an application that helps to map your friends according to the geolocation details they added to their profile. As your social network is more global so you will find that your friends are more spread around the world. As you’ll see for me there’s a lot of clustering around London where most of the people I know on Facebook are living.
There is a nice spread in other parts of the world. Some of them are in Australia, various parts of Asia, Africa, and the US. As you zoom in you can see a nice amount of detail as to where they live. With high-resolution satellite images you can see the street they live on. They can see the street where I live as well.
This is one of the Facebook applications which I feel is not there to fill your profile with junk but rather to provide an interesting insight as to the global spread of friends you’ve met over the years.
