Achmiz argues that it makes more sense to define each page as 'new' vs 'old', and disable the black-stars based on that, rather than on whether it's a blog or not. This is more work, but makes more sense (and we might want to do other things based on that binary variable, like emphasize the created date at the top of the page, to warn readers that something is recent and thus still half-baked). So we're implementing that now.
