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
