I just happened to end up on the ‘Harry Potter’ wikipedia page to check the book series’ sales. I noticed that J.K. Rowling was referred to as an ‘English’ author. Given her ties with Scotland, and her political attachment to PM Brown, I thought that ‘English’ was not the most appropriate definition for her. So I changed it to ‘British’.
UPDATE: the wikipedia establishment stroke back, and changed ‘British’ back to ‘English’. So I had to change it again. But I can’t do that all day: so if someone finds ‘English’ again, well, you know what to do.
UPDATE 2: there is now an ongoing discussion on whether it should be ‘English’ or ‘British’ here.
