I was wondering how I could use Facebook to test the six degrees of separation theory. Do I just pick someone I know or someone famous?
I don't fully get how it works as wouldn't I just search their name or does it mean their needs to be a link between us. e.g. Searching for Brad Pitt. Do I need to be friends with someone who is then friends with someone who is friends with Brad Pitt?
I'm just a bit confused on how it all should work.
Should you be doing them as well?
