This subject underwent extensive research by the now departed Laura Hale: Laura Hale’s answer to In what ways does the Indian Quora differ from the American Quora? Part of that research shows that Indians tend to follow other Indians, and engage with them, and Americans other Americans.

Hence, Nick Nicholas’ answer to Why is the Indian community of Quora termed as “self-contained”?
