I posted the problem on one of the Newsgroups at the time and got my reply back from John Carmack himself (which naturally fixed the problem pretty quickly.)
I remember being extremely excited then, as I'm sure the questioner is now on SO.
You never know who is reading, so don't say anything you couldn't vouch for in real life (which increasingly overlaps with our Internet life)

Which is not unlike how it was when communities where constrained in population. E.g. in ancient Athens for example you could have --if you lived at the right point in time and weren't a slave-- a conversation with the greatest minds of the era, from Socrates to Plato, to mathematicians etc...
So, a "global village" indeed...
[1] "According to the Ancient Greek historian Thucydides, the Athenian citizens at the beginning of the Peloponnesian War (5th century BC) numbered 40,000, making with their families a total of 140,000 people in all. The metics, i.e. those who did not have citizen rights and paid for the right to reside in Athens, numbered a further 70,000, whilst slaves were estimated at between 150,000 to 400,000.[7] Hence, approximately a tenth of the population were adult male citizens, eligible to meet and vote in the Assembly and be elected to office." http://en.wikipedia.org/wiki/History_of_Athens#Geographical_...
And the even more contentious question is: how many are in the same place today? Lack of money when growing up and circumstance can be equally as brute as force to deny someone his "possible future" as anything else. How many readers does HN have that are San Francisco natives and how many that are, say, from Mississippi or Alabama combined?
With ~2 million people in jail, some million homeless and several tens of millions eating with coups and soul kitchens, one of basic differences now is that we have the luxury (hypocrisy?) to blame them instead of some institution like slavery.
