What about the many readers who will be frustrated by not having a direct link to number-one films in countries other than these? The "English" in "English Wikipedia" means that this encyclopedia is written for anyone who can read English. There are more such people in Asia than in North America, more in continental Europe than in the United Kingdom, and more in Africa than in Australasia. And, even if that was not the case, why assume that readers in a particular country will be more interested in articles about their own country than in those about other countries? I read an encyclopedia to broaden my knowledge, not to read about parochial matters, and I would hope that the same goes for other readers.
