What kind of blog is that?

I mean if you navigate to the index https://joearms.github.io/index.html#Index it says that this is actually a Quine.

Yeah, from his WP link quines are, among other descriptions, "self-replicating programs". And in the same blog header he also says it's a TiddlyWiki. That's one of many kinds of TinyWikis, and a rather interesting one in that it's self-contained: The entire source code for its Wikifying is contained as JavaScript within the actual HTML page itself. I guess that's what he means; TiddlyWiki pages are kind of "self-replicating" and therefore kind of quines.
