Fail Log: 6 Degrees of Facebook

I had the idea that one could use the mutual friends network to find how you were connected to anyone on Facebook (celebrities, people worth stalking, etc.). Also, if you wanted to find a contact in the Justice Dept to get the lowdown on a job you're applying for, maybe that person is only a couple of degrees of separation away from you, etc. It turns out that a Facebook app like this has been written, and you can only see the mutual friends of the people using the app. So you would need millions of users before it becomes useful (this app only had 300).
