Because I started reading. I got pretty far, and it was _still_ talking about integer types. The article is very long, and I gave up, not having any idea why I should keep reading. So saying the article isnt about them "at all" is wrong. Maybe, the int type thing is an intro to some other thing? But thats a long intro. So, tl;dr, at least not all the way. Why don't you tell us the point so we have desire to actually read it.
