If you look at screenshot #5, the text is the same size as the text the page is written in, yet looks very different. No slab serifs on 'r' or 'n', and a less quirky 'y' and 'k'. So now I don't know if the page is written in the font it's talking about, or some other font. Confusing.
According to my browsers dev-tools the text on the page is Dossier[0], which happens to be a font by the same author. I admit I also first thought that it would be set in the font its trying to demonstrate.
Yeah, it's different enough to avoid triggering my Comic Sans allergy, but OTOH at least Comic Sans has a clear purpose (comic-style lettering), while this sits in the middle between Comic Sans and a "typewriter-like" font (Courier), and I somehow can't imagine a typewriter with this font...
