Do you think that Asians are discriminated against, perhaps in different ways? I've never been to the Valley and have been curious about its dynamics for some time.
On the ground, there are few social barriers between whites and Asians. The exception is that I seldom saw an Asian man dating a white woman, as a commenter mentions below.
In the tech blogs, the large contributions of Asian people and culture to the Valley are just ignored. It is easier to find a noodle shop than a breakfast place. I think Cupertino had the first majority-Asian city council in the US.
