>Would be curious: Is it US-centered? How much people from LatAm or SEA? EU?
Why would it not be US centered? YC is an US company.
Overall, US + Canada is 50 - 60%. UK + EU is 25 - 35%. You could find post that lands on HN frontage showing their stats.
Probably more to do with HN being a tech community, and the US is the largest highly developed country where a lot of kids can learn tech stuff. So you get a disproportionate number of programmers and related professionals who are American.
If Silicon Valley were in the UK I think most HN contributers would still be American.
Is Facebook US-centered? I don't think that means much.
