Do AMERICANS ignore INDIAN threads and vice versa?

I'm neither American nor Indian. But I see the point of replying to a post which you think is relevant to you. By relevance, I do not mean that the post should be of quality contenct. I guess people would consider the country which the user came from. For example, when Indians talk about Bollywood, you wouldn't be expecting other nationalities to respond except if it's all about the Bollywood actresss Shila Shetty. So that's it, it depends on what is being posted. If the topic is regional, some nationalities will ignore it. If it's global, many would surely respond. This regional aspect, I believe, is not sole about racial discrimination. It has something to do with one's experience in one's own country.
