Hi Stefano!
That's amazing!
I it is really funny to find yourself and your relationship to other
community members or the community in common.
BTW, I've got one question:
If you press on "Start" the whole graph is moving.
Does this have a particular meaning (e.g. how the releationships change
over time) or is it just eye fancy ;-)?
Bye,
Andreas
