You need an activity to connect them, though. Erdos numbers are based on collaborative math publications. The problem here is that some are researches (you could do cs publications), some are software developers (torvalds, gates), and some are just really influential.

Ah, now I understand. This would be a really cool thing. With this data we could also create graphs of relationships and we also could find the Erdös of IT.

But I think for me this is to much effort to create something like this (One would need to study all the resumes of the giants to find out their relationships and so on.)

But if anyone wants to create something like this I more then willing to give them my list of giants.

What would be the connection?

Perhaps: Has contributed to the same software project

Yes, but what is their Bacon number?
