I don't agree with the answers you're getting. The US is a subset of the world. People into computers in the US is a subset of the US population, which is also grouped differently than in Europe. HN is in turn a subset of those people.

The US is more right-wing than Europe. People into computers in the US are fairly affluent, probably even more so compared to Europe. HN readers are more business focused and less hacker/community focused than other people into computers.

Generalizations of course, but I would bet few of the people answering you have been to CCC for instance.
