New feature for Facebook

I don't know if you are familiar with the '7 degrees of separation' hypothesis, which basically states that

"any 2 people in the world are separated by at most 7 degrees of separation."

This means that someone in Alaska could well be the friend of the cousin of the friend of the teacher of the pen pal of your sister's friend. In essence, you can connect any two people with such a line.

I don't know how accurate this hypothesis is, but when I think about it it seems pretty plausible to me. I mean, I'm sure it's a pretty common occurrence for Facebook users to go like 'Eh?! You know jane ah? she's from my secondary school!' which just shows the coverage of social networks.

Ok sorry that was a random digression about what I wanted to blog about. This post isn't about this 7 degrees of separation, but for a new feature for Facebook, that is, a 'Circle of Friends' or 'CoF' for short.
