Sure - in this day and age of the non-religious: f-o-a-f != f

But actually, in the set of people who are 'devout', this fact isn't so true. The religious are connected in this way.

And the thing is .. this foaf thingy .. Its not actually supposed to be a useable metric for you - its a metric for people who want to get to know you without .. getting to know you. If I know all your friends, and all your friends'-friends', then I can assume a few things about you that might be very true.

If I'm a marketer, then great that there are services that get people to self-organize in this way, so that they can be sold things, better.
