six or 4.47 degrees of separation

how does this fit with pi... and heathers wish for avpi lab
rather than idea lab... perhaps more of shirkys cognitive surplus playing on a connectedness lab or space

like diameter is furthest distance in a circle (circle of friends... circle of possibility... circle of life)
and pi... how many times to get back to start ...on that circle.


so ...will we find the limit converges to 3.1415degrees of separation. even at furthest distance... and even no matter how large the circle....?

how cool is that.
how much the transparency of the web is teaching us... and giving us confidence in how close we all really are
