A blog is (by default) additive. You append by adding a new post, the items are ordered by date of creation, and you rarely remove old content.
If you look at the author's /now page, it's very clearly not that: https://sive.rs/now.

However it's very obviously not a blog since a blog encompasses a much larger concept. You can blog about your hobbies, interests, specific topics, related or otherwise. I'm confused at the OP's confusion between a blog and a /now page.
Hm? And you can also blog the same content as you put on /now. Many people do. A public journal of whatever is going on in author's life is pretty much the OG idea of a weblog.
