I think the intent was making a blog has additional requirements one might not need to just make a website, a la what the "The Hard Way" section tries to argue against, not a claim a blog is not also a website (anything the page says not to use will also lead you to having a website as well - just with more than minimal work).

E.g. the section covering RSS for your post is longer than the section covering HTML, you don't really need a fixed structure, and you don't need to think of a story to write unless that's what you want to do. You can just post a picture of your cat and try to add googly eyes later if that's what floats your boat. Or just "Hello World" and let your mind go from there.
