How does it work?
It’s simple. This application will get a list of all your friends’ friends (second degree friends) and count who appeared the most. You can then use the application to discover those common friends that are not on your list. However, there’s one catch: You’ll have to get your friends to add this application, otherwise we wouldn’t be able to find their friend lists.
I really like this idea. Facebook already does it to an extent, but only shows you friends you have directly in common when you view a particular person’s profile (see picture). If you have tons of friends, this could be tedious and you may never realize that some of your friends are mutual. More over, if many of your friends share a common friend, there’s a good chance you might know that common friend too. Unfortunately, More Friends is limited by Facebook’s FBQL restrictions on pulling friend lists only of those that have the application installed. This is awesome for More Friends (since it forces you to invite everyone you know), but too bad for me, because I can’t go about inviting my friends to install every application I test. And mind you, I test a lot of apps! I compliment them for being so up front about this from the get go, even before installing the application. To kick the wheels, I invite a few of my close friends that are used to my Facebook request spam.
I wait a few minutes for the app to update, as it appears that it does not get updated in real-time.. When it does update, I have new results under the “More Friends” tab.
Sure enough, it found a friend Rusty that I haven’t yet added to my contacts. Caveats aside, I think this is a great tool for finding lost contacts. I am tempted to invite spam everyone, to see who’s on Facebook that I haven’t yet befriended.
