::I'll have a look at redrafting the stuff in (1) if you're going to look at (2). However, I'm not sure the reasoning provided is valid. "The sky is blue" example was picked because everyone on Earth (i.e. our readership) should be aware of this and the statement should not, therefore require validation. Looking at the suggested example, the article on horses does not provide any validation for the number of legs on a horse (the average, of course, is less than four). Perhaps more relevant to this article is the unreferenced assertion that the English-speaking world measures the height of a horse in hands. Do these claims need references? I don't think so, but since I've just challenged them I've created a whole lot of work for someone. Is that what Wikipedia is about?
