YC/HN is global. You read the comments and you gain insight from people in Bangladesh, in Australia, in Japan, anywhere where idealistic techies are. The only country that realizes the potential is the US and the only region where you can live the lifestyle is the West-Coast and this is why it sometimes may feel like a bias.

Anyway, I fail to see the reason behind this. Especially since the startup scene in Berlin (and London) is mostly driven by business graduates and less by techies. If you want to find similar people, you can use meetup or similar.
